Smith (knee) is expected to begin training camp on the PUP list, making him "doubtful" to play in Week 1 against the Bengals, Rich Cimini of ESPN New York reports.
The recovery timetable for an ACL tear has dwindled in recent years, but such injuries need to be explored on a case-by-case basis. Considering Smith's rookie campaign came to a close in Week 14, it's no surprise that the final stages of his rehabilitation will extend into training camp, at least, and potentially into the regular season. Once healthy, though, he'll have a prime opportunity to succeed in a receiving corps that's unproven behind Brandon Marshall and Eric Decker.
Wilkerson (leg) is not expected to attend the Jets' offseason program, NFL.com reports.
Wilkerson, who is still rehabbing from the broken fibula he suffered in Week 17, has yet to sign his $15.7 million franchise tag, as he continues to seek a long-term deal with the Jets. While his stance on a new contract could lead the Jets to entertain trade interest in him during the draft, Wilkerson's career-best 64 tackles and 12 sacks make him one of the league's best defensive lineman, and someone New York could obviously use after losing nose tackle Damon Harrison this offseason.
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.
