Horton has an opportunity to see an expanded role on defense in 2018, Jourdan Rodrigue of The Charolette Observer reports.

Horton is entering his sixth season in the league, all of which have been with the Panthers. The 28-year-old recorded 360 defensive snaps in 2017, but after the release of Charles Johnson this offseason, the Panthers will need someone to take on more reps in rotation with veteran Julius Peppers. If he impresses during training camp, Horton could be line for a major uptick in his workload this season.

Brown has been impressing throughout team activities this offseason as he competes for a starting role in 2018, Jim Wyatt of the Titans' official site reports.

Brown has been making all the right moves this offseason but he is still not guaranteed a regular role on defense in 2018. Wesley Woodyard, the team's leading tackler in 2017, returns along with the addition of first-round selection Rashaan Evans. The team also signed veteran linebacker Will Compton (foot), who spent his first five seasons with the Redskins.

Bell (shoulder) was cleared to participate in team drills during spring workouts, Andrew Krammer of the Minneapolis Star Tribune reports.

Now healthy, Bell split reps with the starting offense with David Morgan while Kyle Rudolph (ankle) works his way back into action. However, Bell is not a great bet to continue seeing first-team work when Rudolph is fully healthy, especially with fifth-round rookie Tyler Conklin competing for a depth role at tight end as well.

Longacre (back) was a limited participant in offseason workouts, Myles Simmons of the Rams' official site reports.

Longacre was held out of team drills while he rehabs a back injury that required surgery last December. It isn't clear if the linebacker will be fully ready to go when training camp opens. If he isn't, seventh-round rookie Justin Lawler -- who received the majority of reps with the starting unit in minicamp -- will likely open training camp with the first-team defense.

Barron (shoulder) was a limited participant in the Rams' offseason program, Myles Simmons of the team's official site reports.

Barron underwent shoulder surgery this offseason and wasn't allowed to do any team drills this spring. While it isn't clear if he'll be completely free from his restrictions when training camp arrives, Barron is nonetheless slated to play a huge role in the Rams defense this season. In fact, defensive coordinator Wade Phillips said the linebacker could potentially be the team's defensive signal-caller.

Allen (back) was an active participant through OTAs and minicamp, Vincent Bonsignore of the Orange County Register reports.

Allen finished the 2017 campaign on injured reserve with an unspecified back injury he suffered in December. While he's now healthy, Allen remains the team's No. 3 quarterback behind Jared Goff and Sean Mannion.

Johnson was released by the Grizzlies on Sunday, Shams Charania of Yahoo! Sports reports.

Johnson played in just four games with the Grizzlies last season and will now released this offseason in order to open up a roster spot. Look for Johnson to try and latch on with another team prior to training camp, though he's not guaranteed a final roster spot elsewhere and is unlikely to become a relevant fantasy option.

Muscala exercised his $5 million player option for the 2018-19 season Sunday, Adrian Wojnarowski of ESPN reports.

Muscala suited up for just 53 games this past season, though he still set career-high marks of 7.6 points and 4.3 rebounds across 20.0 minutes. Despite the improvements, Muscala was unlikely to field contract offers that offered more than $5 million, so he'll understandably remain with the Hawks and opt in to his option. The Hawks bring back the likes of John Collins, Dewayne Dedmon, and Miles Plumlee, so Muscala is unlikely to see his playing time increase much, if at all, ahead of the upcoming campaign.

Teodosic has opted into the final year of his contract, Broderick Turner of the Los Angeles Times reports.

As expected, the Serbian guard will try to don the Clippers jersey for one more season, but the team still holds the right to cut him and pay him a fraction of what he is currently scheduled to make. Last season with Los Angeles, Teodosic averaged 9.5 points and 4.6 assists per game while coming off the bench. If the team decides to hold on to him, he'll face Austin Rivers once again in the competition for minutes. He's also facing a log jam with the addition of the recently-drafged Shai Giglgeous-Alexander, so how quickly he comes along could play an impact on how long the Clippers decide to keep Teodosic.

Osman will join the Cavaliers' summer league team, Ashish Mathur of AmicoHoops.net reports.

Osman, a second-round pick in 2015, made his NBA debut last season for Cleveland. He appeared in 61 games, averaging 3.9 points and 2.0 rebounds across 11.0 minutes while hitting 36.8 percent of his threes. Osman also drew 12 starts, posting 9.2 points, 3.5 rebounds and 2.5 assists in 23.4 minutes during those contests.

Anthony has exercised his $27.9 million player option, Shams Charania of Yahoo Sports reports.

Anthony set career lows in points (16.2), field-goal percentage (40.4), free-throw percentage (76.7) and assists (1.3) last season -- his first year with the Thunder. With that being the case, it was unlikely he would garner a bigger contract in free agency. That said, if Paul George ends up declining his player option and leaving the team, Anthony could see a more featured role in the Oklahoma City offense.

Green will accept his $10 million player option for the 2018-19 campaign, Jabari Young of the San Antonio Express-News reports.

Green just turned 31 years old and is coming off another down year shooting the ball from distance, which may be driving his decision to accept his player option rather than test the open market. From the 2011-12 season through the 2014-15 season, he made 42.3 percent of his shots from three. Over the past three campaigns, that number has dropped drastically to 35.7 percent.

Carlson signed an eight-year, $64 million contract with the Capitals on Sunday, Bob McKenzie of TSN reports.

As an unrestricted free agent, Carlson could have started talking with other teams Sunday, but the Capitals managed to lock up their top defenseman before he could even do so. Carlson led all defensemen in points last season when he tallied 15 goals and 53 assists. He has essentially doubled his salary as a result.

Ouellet was placed on unconditional waivers Sunday, Renaud Lavoie of TVA Sports reports.

After totaling just seven assists in 45 games with Detroit last season, the team is ready to part ways with the 24-year-old defenseman. Assuming he clears waivers, Detroit will buy out the final year of his contract and Ouellet will hit the free agency market.

Kero was traded to the Canucks from the Blackhawks on Sunday in exchange for Michael Chaput.

Kero saw action in just eight games at the NHL level last season, as the bulk of the campaign was spent in the AHL. He'll now head to Vancouver; despite the move, Kero likely won't see a huge boost in playing time and can be avoided in the bulk of fantasy drafts.

Chaput was traded to the Blackhawks from the Canucks on Sunday in exchange for Tanner Kero.

Chaput saw action in just nine games at the NHL level last season, spending most of his time in the AHL. In 55 games with AHL Utica, Chaput registered 42 points, which was second most on the team. Despite the change in scenery, Chaput still likely won't get on the ice enough to be a viable fantasy contributor most nights.

Soshnikov signed a one-year, one-way contract extension with the Blues on Sunday, according to his agent, Dan Milstein.

Soshnikov played in only 12 games last season for the Blues after being traded from Toronto, collecting two points on one goal and one assist -- unfortunately, an upper-body injury largely cut into his potential. However, the Russian is still only 23 years old and only one year removed from the 2016 season with Toronto when he scored five goals and racked up four assists in 56 games. He might be worth keeping tabs on if he can stay healthy, but his value to fantasy owners seems to have a relatively low ceiling.

Wideman agreed to a one-year contract extension with the Senators on Sunday.

The defenseman is coming off a hamstring injury and missed 66 games this past season, but that didn't stop the club from extending the veteran for one more year, as he has now been cleared to continue all athletic activities. Wideman has been with Ottawa since he went 100th overall in the 2009 NHL Draft; he's since posted 38 points (14 goals, 24 assists) in 156 games.
