JACKSONVILLE – The theme on Wednesday was detail.
As Head Coach Gus Bradley emphasized that, he and the Jaguars remained uncertain about the status this week of two of the team's top players.
Tight end Julius Thomas and defensive tackle Sen'Derrick Marks, neither of whom has played during the 2015 regular season, continued to practice on a limited basis Wednesday. Bradley said it remains in doubt whether they have a chance to play Sunday.
Each worked limited last week before being deactivated Friday.
"It's all based on the doctors; it's hard for me to say," Bradley said as the Jaguars (1-3) prepared to play the Tampa Bay Buccaneers (1-3) at Raymond James Stadium in Tampa, Florida, Sunday at 1 p.m.
"I think they both face different challenges."
Thomas, who signed as an unrestricted free agent in the offseason, sustained a hand injury in the team's preseason opener and has not played since. He worked as planned Wednesday. Working limited, he caught passes with protection on his hand to limit flexibility. He previously has had a cast on his injured hand.
"He did what he was cleared to do," Bradley said. "The other things he still couldn't do."

Asked if Thomas could up his workload Thursday, Bradley said, "We'll push it and see, but it's really going to be on our trainers and doctors."
Marks, the team's sacks leader with 8.5 last season, has yet to play in the preseason or regular season after undergoing reconstructive knee surgery in January. Bradley said while Marks' knee is improving he is still working to be able to face the "play-after-play rigors that it takes to play in the defensive line."
"That's the challenge he faces," Bradley said.
Bradley said the Jaguars pushed Marks in practice Wednesday, too.
"We limited some of his reps, but we got him in some one on ones today," Bradley said. "We'll evaluate the film (Wednesday) night and see where he's at."
Bradley on Monday also said attention to detail was a major emphasis Wednesday. On Monday, a day after the Jaguars committed 13 penalties in a loss to the Colts in Indianapolis, Bradley spent extensive time in his next-day press conference talking about self-inflicted wounds, focus and discipline.
"We started the week today with an intro to Tampa, but more importantly I think it was a message about being on the details," Bradley said. "Everything matters to us. Everything on the practice field, in the meeting rooms, how we go about our business … I thought it was a very, very good practice today … very good.
"I saw a lot of guys competing and I saw them competing at the details as well, so it's off to a great start. We have an important matchup this weekend and how we go about it I think is important."
The Jaguars released their first injury report of the week Wednesday, with wide receiver Allen Hurns (ankle/thigh), tight end Marcedes Lewis (knee), linebacker John Lotulelei (concussion), wide receiver Marqise Lee (hamstring), middle linebacker Paul Posluszny (ankle), defensive end Chris Clemons (knee), safety James Sample (shoulder) and running back Denard Robinson (knee) not practicing.
Hurns, Lewis and Clemons all finished Sunday's game, while Lotulelei reported symptoms following the game. Posluszny and Sample left the game with injuries. Lee and Robinson did not play in Indianapolis.
As was the case with Marks and Thomas, safety Sergio Brown (calf) worked limited after missing this past Sunday's loss to the Colts.
Cornerback Aaron Colvin (shoulder, limited) took full repetitions with limited contact.
