Jackson made cuts, caught passes and stayed after practice Friday to do extra work, signaling his continued improvement as he recovers from a knee injury. Still, Bucs coach Lovie Smith wouldn't commit to Jackson being ready to return to game action.
"That's why we can't really tell you on a Friday," Smith said. "We have 48 hours or so before the game. Once you get close, every hour counts. As soon as Vincent is ready to go, we're ready for him."
Smith said that Jackson's progress since Wednesday was noticeable. Jackson was a limited participant in practices Thursday and Friday.
"I think you all have seen him running around," Smith said. "He's getting closer, which is right on schedule. But hopefully, he will be able to [play]. But we'll see."
Jackson, 32, has 319 yards and two touchdowns on 21 catches this season. With him sidelined the past three games, wide receiver Mike Evans has served as the Bucs' main receiving threat, totaling 324 yards on 19 catches in the span.
Meanwhile, Smith said that tight end Austin Seferian-Jenkins (shoulder) still hasn't been cleared for contact. Seferian-Jenkins, who last played in a Week 2 win over the New Orleans Saints, is questionable after limited participation in practices Wednesday through Friday.
"He's doing everything he's supposed to do," Smith said. "But the guy's been injured, and he hasn't been cleared. So once he's cleared, we'll get him back out there full time, full speed, all that. He's not there yet."
In other injury news, defensive end George Johnson (calf) is out and defensive end Josh Shirley (calf) is doubtful. Guard Ali Marpet (ankle), center/guard Evan Smith (knee) and defensive end Jacquies Smith (ankle) are questionable. Safety Major Wright (hamstring) is probable.
