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.
Carroll (leg) has agreed to re-sign with the Eagles on a one-year contract, ESPN reports.
Carroll started the first 11 games of last season before suffering a broken fibula in a Thanksgiving loss to the Lions. He may have to compete for a starting job in 2016, as the Eagles traded away Byron Maxwell but did sign Leodis McKelvin. 2015 second-round selection Eric Rowe also figures to compete for a starting spot on the outside.
Brooks (neck) was placed on injured reserve Tuesday.
Neck and shoulder issues cost Brooks time recently, even forcing him into the concussion protocol, though it's not entirely clear whether his placement on IR is related or due to a new injury. Brooks played primarily on special teams this season, recording 12 total tackles (11 solo).
