Ayers (ankle) practiced in a limited capacity on Wednesday, Greg Auman of the Tampa Bay Times reports.
Ayers participated for the first time since suffering the ankle injury Week 2, albeit in shorts as the Buccaneers limited his activity. If he's unable to return to game action Sunday against the Raiders, Noah Spence figures to once again get the start at defensive end.
Martin (hamstring) didn't practice Wednesday, Greg Auman of the Tampa Bay Times reports.
Already beset by one setback, Martin will be treated with kid gloves by the Buccaneers as he rehabilitates the balky hamstring that has sidelined him since Week 2, per Auman. As a result, the training room will be Martin's domain until he's cleared to return to the practice field. In the interim, the Bucs will entrust Jacquizz Rodgers with a particularly hefty workload, which has equated to 56 carries for 255 yards and six catches for 37 yards over the last two contests.
McDonald (hamstring) was a limited participant in practice on Thursday, Jenna Laines of ESPN.com reports.
McDonald missed Week 7's win over the 49ers due to a hamstring aliment. His limited participation the past two days makes him questionable for Sunday's tilt with the Raiders, but his status in Friday's practice session will be key in determining his availability. Should he be ruled out, look for Akeem Spence to get the start.
Bell (concussion) reached an injury settlement with the Buccaneers on Thursday, Aaron Wilson of the Houston Chronicle reports.
Bell suffered a concussion in Week 4's preseason finale against the Redskins, leaving him on the sidelines for an extended amount of time. The team decided to part ways with wideout instead of holding him on IR for the year.
Jones (knee) returned to practice Thursday, Jimmy Durkin of the Bay Area News Group reports.
Jones was spotted back on the field after not playing since Week 3 due to knee aliment. Should he be cleared for Sunday's tilt with the Buccaneers, expect him to see his reps significantly monitored, in which case DeAndre Washington and Jalen Richard could see increased action.
Smith (suspension) has applied for reinstatement into the NFL, Vic Tafur of the San Francisco Chronicle reports.
Smith's one-year suspension that he was serving for a violation of the league's substance abuse policy is nearing an end, and after entering a treatment center in late July, Smith will once again attempt to make a return to the NFL. Having been suspended and under investigation multiple times over the past few years, Smith will have a lot to prove to the league if he wishes to play once again.
