"It's nice to get them out here and get them the reps that we emphasize on Friday," coach Norv Turner said. "I would love to have them practicing Wednesday, Thursday and Friday, but that is not where we are at right now. But I'm optimistic all three will be able to play."
Gates, who missed two of the last three games with a torn plantar fascia in his right foot, practiced for the first time this week, in a limited role. He likely won't know his status until the hours leading to kickoff.
"Can I sustain it for a whole football game, and if not, can I still come in and contribute on certain plays?" Gates said. "That is just where I'm at with it and we'll see how it feels on Sunday. I get a chance to go out there and warm up and run around -- the whole vibe of when I wake up that morning and how my foot feels and how it feels running around usually determines if I'm going to play."
Floyd, bothered by a hamstring injury, participated in the full practice.
Tolbert practiced for the first time this week as swelling in his bruised hand had prevented him from participating Wednesday or Thursday. Tolbert is the team's leading rushing and has nine touchdowns.
Those numbers were expected to be produced by Ryan Mathews, the team's first-round pick. But a high ankle sprain has derailed his season. Mathews missed the last two games and has missed three overall.
He practiced all this week and will get a share of Sunday's carries. Turner said that if Tolbert is healthy, he remains the featured back.
"I just want to go out there and play again," Mathews said. "It doesn't matter how they're going to use me, as long as I'm back on the field with my teammates. Whether it's one carry or 10 carries, I just want to play."
Unable to practice were wide receivers Vincent Jackson (calf) and Patrick Crayton (wrist), plus starting right guard Louis Vasquez (neck). Crayton has been declared out, with Jackson and Vasquez are listed as doubtful. Neither has practiced all week.
