JACKSONVILLE – Sen'Derrick Marks' progress continues, and it's good progress.
Marks, the Jaguars' veteran defensive tackle, practiced again on a limited basis on Thursday. And to hear him and Head Coach Gus Bradley tell it, he continues to get closer to returning from offseason reconstructive knee surgery.
As for when that will happen, or if it could possibly be Sunday, that's not yet known.
"We just have to wait and see," Bradley said Thursday 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.
Marks, the Jaguars' sacks leader last season with 8.5, spent the offseason rehabilitating after January surgery to repair a torn anterior cruciate ligament sustained in last season's regular-season finale. He has practiced limited the last few weeks, increasing his workload each week.
"The coaches and training staff have my best interest, and aren't just going to throw me out there," Marks said. "I continue to work as if I'm going and wait until they tell me when I'm going."
Marks said his work Wednesday in pads was "all live."

"It was, 'OK, let's see what you got … you think you're ready; we think you're ready … we're going to find out today,'" he said. "I really had that mindset. As long as I was out there going with the guys and going through the drills, it was more of a positive for me to see that I could actually go out there and do it."
Bradley said Marks appeared "not quite there yet" when reviewing Wednesday's practice, "but hopefully today (Thursday) a better showing."
"I think there are signs that he is coming back from an injury, where I see a little bit of rustiness, I would say," Bradley said, adding, "His effort and want-to and all that is there. He just needs some reps."
Bradley said Marks got extensive work in practice Thursday.
"He took quite a few reps," Bradley said. "I think that's the thing we need to look at – how much did he progress just from yesterday?"
And while Bradley said the plan could be to have Marks play a limited 10-to-15-play workload when he first returns, he said Thursday "I'm not sure if he's ready right now to do that."
Marks said being able to practice in recent weeks – something he could not have done had he been left on the physically unable to perform list after the preseason – has been a positive. He said it's his hope that he can play at close to his 2014 level upon his return.
"That's been a mental thing for me, but I as long as I'm out there and continue to go with the guys, I don't think they'll put me out there until I'm at least way more than half of what I was," Marks said.
Bradley on Thursday said the Jaguars had a "good practice."
"It's not just effort, and energy, and enthusiasm," he said. "What I liked about today was yesterday we talked about the details and the message today was to come back and apply those details to today's practice. The emphasis was different, but doing it day after day – communication, line calls, the defensive calls and doing it start to finish … that was really the message today. I was very pleased with how it went.
"Everybody's just got to do their job. That's what it comes down to – play after play. That consistency is what we need to continue to build."
Safety Sergio Brown (calf) worked full Thursday after working limited Wednesday, and tight end Marcedes Lewis (knee) and defensive end Chris Clemons (knee) worked full after not practicing on Wednesday.
The following players worked limited Thursday: Cornerback Aaron Colvin (shoulder), Marks, tight end Julius Thomas (hand) and wide receiver Allen Hurns (ankle/thigh).
Wide receiver Marqise Lee (hamstring), middle linebacker Paul Posluszny (ankle), linebacker John Lotulelei (concussion), safety James Sample (shoulder), cornerback Davon House (illness) and running back Denard Robinson (knee) did not practice Thursday.
Bradley said the team has not ruled out Posluszny, and that a determination on the status of the starting middle linebacker could be made Saturday or Sunday.
"We knew kind of going into this that this would be day after day," Bradley said. "It would not surprise me if he didn't go (Friday) in practice, but still, we're OK with that. I think we anticipated this might happen and would not be surprised if it happened again (Friday)."
