Caldwell suffered a hamstring injury during the onset of training camp, Nate Ulrich of the Akron Beacon Journal reports.
It's currently unclear whether the hamstring was merely tweaked or if Caldwell has suffered something worse. Either way, there has been no timeline provided for his return. When healthy, the Browns' fifth-round pick will compete for a role out of the slot.
Bryant (suspension) pleaded guilty to misdemeanor drug charges on Wednesday and could have his four-game suspension prolonged, Scott Petra of the Elyria Chronicle-Telegram reports.
Bryant was indicted in February on felony drug charges and originally pleaded not guilty, but changed his stance on Wednesday, pleading guilty to misdemeanor charges. As a result, the outside linebacker will receive 68 days probation which will expire on Oct. 3, the same day he is schedule to return from his original four-game suspension. However, now that Bryant has changed his plea, his case will yet again be reviewed under the league's policies, which could potentially lead to a lengthier suspension. Bryant recorded 5.5 sacks in 14 games in 2015.
Gordon (suspension) nabbed three of his six targets for 29 yards during Thursday's preseason game versus the Bears.
Gordon, who looked liked his former self throughout the preseason, will have to wait until Week 5 against New England before he's allowed back on the field. He worked with the second team Thursday in order to get some final reps in before his suspension kicks in on Saturday. If he can keep up his rapport with Robert Griffin when he gets back, he'll be a welcome addition to a receiving corp that's already flush with talent.
Bryant (chest) has been placed on the injured reserve list and will sit out the entire season, Mary Kay Cabot of Cleveland.com reports.
Entering his eighth NFL season and fourth with the Browns, Bryant was a lock to start at defensive end after a 2015 campaign which saw him record a career-high and team-leading six sacks. The torn pectoral muscle he suffered earlier this month was originally thought to keep him out 4-to-6 months, making November the soonest possible return date. Rather than push his recovery in the hopes of a return the team decided it best to shut him down for the season. Carl Nassib appears first in line to replace Bryant, but John Hughes and Dylan Wynn could see some extra snaps as well.
Mitchel (hamstring) has been released by the Colts after reaching an injury settlement with the team, George Bremer of The Herald Bulletin reports.
Mitchel missed all of last season due to injury, and entered this season on the IR. He injured his hamstring in the team's final preseason game. The 24-year-old has yet to play in a regular season game.
Miller was placed on the active/no-football list with an undisclosed injury on Tuesday.
The severity of the injury is still unknown, but Miller, a rookie undrafted free-agent, will now miss the beginning of his first training camp. Fellow tight end Darion Griswold was placed on the PUP list, leaving the Colts with five healthy tight ends to open up training camp.
Jones will be suspended for the first four games of the 2016 season for violating the NFL policy on PEDs, Ian Rapoport of NFL.com reports.
Jones missed the entire 2015 season due to torn ligaments in his ankle and did not participate in spring practices. He may have been sidelined to start the season even without the suspension, but this still hurts Indy's depth on the defensive line.
