COSTA MESA, Calif. -- Melvin Gordon did not practice Wednesday due to a sprained left ankle, and Los Angeles Chargers head coach Anthony Lynn indicated that he would not know until Friday at the earliest if his star running back will play in the team's regular-season finale against the Oakland Raiders.

"He's day-to-day," Lynn said. "If it's something he can play with, then he'll play. But right now we won't know until the end of the week."

However, Gordon did not mince words when asked how he felt in the locker room before practice on Wednesday.

"I'm good," Gordon said. "I'll be ready on Sunday."

Gordon suffered the injury late in the Chargers' 14-7 victory over the New York Jets on Sunday. He limped off the field and did not return.

Gordon has been listed as questionable four times this season due to knee, shoulder and foot issues and has played and started in all four games. The Wisconsin product topped the 1,000-yard mark for the first time as a pro this season, with 1,012 rushing yards through 15 games, and seeks to play in all 16 regular-season games for the first time in his three-year NFL career.

At 8-7, the Chargers still have a chance to make the playoffs with a win over the Raiders and some help from other teams.

"Melvin's a tough player, a tough guy," Chargers quarterback Philip Rivers said. "You know he's going to do everything he can. This isn't a Week 3 game. I know they all are important, but one where you think, 'Gosh, is this something that could linger?'

"This is the game. Either you have a chance to extend the season or not, so you know he's going to do all he can."

Along with Gordon, safety Adrian Philips (ankle) and tight end Jeff Cumberland (illness) did not practice for the Chargers on Wednesday.

However, returning to the field as limited participants after missing last week's game against the Jets were left tackle Russell Okung (groin), defensive tackle Corey Liuget (knee) and middle linebacker Denzel Perryman (hamstring).
