Both are listed as doubtful, but Seferian-Jenkins was the only one of the two who practiced this week. Still, Bucs coach Lovie Smith said he'll let Jackson, an 11-year veteran, decide whether to play.
"[If] a veteran player wakes up Sunday morning and says, 'I'm ready to go' and trainers say he's ready to go, we're going to let him go," Smith said. "That's why I don't rule guys out on Friday. He didn't have a broken leg. He doesn't have a concussion."
If Jackson doesn't play Sunday, the absence would end his streak of 74 consecutive games. He has become one of quarterback Jameis Winston's favorite targets, totaling 319 yards and two touchdowns on 21 catches. Jackson is tied with Mike Evans for the team lead in receptions, and he's second to Evans in receiving yards.
Seferian-Jenkins, who has missed the past four games, was seen catching passes in the early part of practice Friday. He had seven catches for 139 yards and two touchdowns before being sidelined.
"He's making progress," Smith said. "When you have an injury that's taking a little bit of time, you have to measure that progress, and we have. ... Doing things on the football field is going in the right direction. But he's not 100 percent yet."
In other injury news, offensive tackle Reid Fragel (concussion) and defensive tackle Tony McDaniel (groin) were ruled out. Safety Major Wright (hamstring) and defensive tackle Clinton McDonald (pectoral) are doubtful.
