Walford (knee) will likely be cleared before training camp, ESPN's Adam Caplan reports.
Walford is sitting out the first round of OTAs after injuring his knee in an offseason ATV accident. He may miss out on a few reps, but he should still have every opportunity to push for an increased role, likely at the expense of Mychal Rivera. The 2015 third-rounder caught 28 passes for 329 yards and three scores on 51 targets as a rookie; Rivera had 32 receptions for 280 yards and a touchdown on 46 targets.
Ball (knee) is "doing everything" and expected to be "ready to roll" for the offseason program by Raiders' GM Reggie McKenzie.
Ball emerged in Week 5 of last season by holding Denver TE Owen Daniels without a catch on five targets. The performance earned him his first career start versus San Diego in Week 6, but shortly into the game he suffered a knee sprain and was ruled out by halftime. Ball will serve as depth for an imposing Raiders' outside linebacking corps in 2016 behind Khalil Mack, Bruce Irvin, Malcolm Smith and perhaps Aldon Smith (suspension), should he return in November.
Reece has been suspended four games for violating the NFL's policy on performance enhancing drugs, CSN Bay Area reports.
Reece, who will sit out Sunday's season finale against the Chiefs, is thus eligible to return to action after the Raiders' third game of the 2016 season. In the meantime, he can participate in all of the team's offseason and preseason practices and games.
The Raiders and Smith (suspension) agreed to a two-year contract Monday, the team's official site reports.
In the midst of a one-year suspension for another violation of the NFL's policy for substances of abuse, Smith will remain where he spent the first nine games of the 2015 season, when he contributed 3.5 sacks among 28 tackles to the Raiders' pass rush. It remains to be seen whether he'll be strictly contained to a one-year ban, as the commissioner's office has been known to do their due diligence once a suspended player applies for reinstatement. Depending on further adjustments made to the defense in the offseason, free-agent addition Bruce Irvin appears set to man strongside linebacker in the meantime.
Wilson, who re-fractured his left foot Tuesday, is out indefinitely.
Per the report, Wilson -- who missed the last five games of the 2015 season after breaking the same foot -- will undergo surgery this coming Monday and is thus a candidate to open the season on the PUP list. With Wilson ailing, look for Eddie Royal, Josh Bellamy and Marc Mariani, as well as Cameron Meredith, Daniel Braverman and Deonte Thompson to jostle for slotting on the Bears' wideout depth chart behind top options Alshon Jeffery and Kevin White.
The Bears and Bolden agreed to a contract Thursday, the Chicago Tribune reports.
The defections from head coach John Fox's previous employer, the Broncos, continue, as Bolden is the fourth such player to move from Denver to Chicago this offseason. In four seasons in the Mile-High City, Bolden served primarily on special teams, racking up 27 tackles in that domain while returning at least 13 kickoffs on three occasions. Expect him to serve in a similar capacity with the Bears.
McPhee (knee) will miss this week's minicamp, and head coach John Fox was noncommittal as to whether McPhee will be ready for training camp in July, reports Rich Campbell of the Chicago Tribune.
McPhee had arthroscopic surgery on his knee shortly after the 2015 season, and was not expected to be at full speed until training camp, so this isn't shocking news. However, having the outside linebacker at full strength for the regular season will be vital to the Bears' pass rush, as McPhee recorded five sacks in the first seven games of 2015 before being slowed down by the knee injury.
