ORCHARD PARK, N.Y. – Buffalo Bills running back Fred Jackson has been cleared to play at Indianapolis this weekend after passing a series of NFL-mandated concussion tests.

Jackson says he felt good before practice Wednesday, and coach Chan Gailey added that he expects the running back to play Sunday. Despite having Jackson back, Gailey said C.J. Spiller will remain the starter and get a majority of playing time.

That’s a switch in philosophy after the two had been splitting time before Jackson was hurt in a 37-31 loss at New England on Nov. 11.

Spiller leads the team with 723 yards rushing and four touchdowns, and has 336 yards receiving and a touchdown. Jackson had missed two games after spraining his right knee in the season opener.

Jaguars place QB, receiver on IR

The Jacksonville Jaguars have placed quarterback Blaine Gabbert and receiver Laurent Robinson on injured reserve, ending their season.

Gabbert hurt his right forearm in Sunday’s loss at Houston. Chad Henne replaced him and threw for 354 yards and four touchdowns.

Gabbert also has a torn labrum in his left shoulder that needs surgery. The Jaguars (1-9) figured it would be better to get it done now.

Bounty ruling to come in December

Former NFL Commissioner Paul Tagliabue has advised league officials and players implicated in the NFL’s bounty probe that he plans to complete all hearings by Dec. 4 and make a ruling shortly after.

In a document obtained Wednesday by The Associated Press, Tagliabue directs the NFL to produce key witnesses in the New Orleans Saints cash-for-hits program, including former defensive coordinator Gregg Williams and former defensive assistant Mike Cerullo.

Four players initially were suspended, but those punishments were vacated, and Tagliabue oversaw new hearings. Meanwhile, Saints linebacker Jon Vilma and defensive end Will Smith are still playing. Even as Tagliabue moves the process forward, a federal judge is still considering arguments by players that Tagliabue should be removed as arbitrator because he is biased in favor of the NFL.
