LaDainian Tomlinson, Jeremy Kerley sit

FLORHAM PARK, N.J. -- The New York Jets probably will be without LaDainian Tomlinson for the second straight game.

The future Hall of Famer hasn't practiced since spraining his left knee 10 days ago, and there's no guarantee he will practice Friday when the team returns from its one-day Thanksgiving break, according to coach Rex Ryan.

"I'm not sure, this could be one of those game-timers," Ryan said Wednesday. "Hopefully, he feels better on Friday."

Tomlinson vowed last week to be ready for Sunday's game against the Buffalo Bills, but he suffered a setback last week in his rehab and experienced another on Monday. He usually does agility drills during the early portion of practice, open to the media, but he wasn't in attendance Wednesday. He also hasn't addressed the media since last week.

The Jets won't push Tomlinson because they will have Shonn Greene and Joe McKnight at running back. Greene hurt his ribs in the first quarter of last Thursday night's loss in Denver, and didn't return even though he was cleared, but he practiced Tuesday and Wednesday and will start.

Rookie wide receiver Jeremy Kerley (sprained knee) also remains up in the air. He, too, hasn't practiced in 10 days, but he told Ryan he'll be able to practice Friday.

"I think they both feel better today, so, hopefully, that's a good sign," Ryan said of Kerley and Tomlinson. "Hopefully, Friday, we can get them out there."

Meanwhile, wide receiver Plaxico Burress practiced for the first time this week after receiving two personal days for charity work.
