PITTSFORD, N.Y. — Running back Reggie Bush wasn’t going to let a freak accident on the concrete surface ringing the Edward Jones Dome field in St. Louis end his career.

Declaring his surgically repaired left knee 100 percent, Bush eagerly looked forward to the opportunity of playing an 11th NFL season – and on his fifth team – after signing a one-year contract with the Buffalo Bills on Monday.

“I’m in shape. I’m full strength. I’m ready to go,” Bush said during a news conference at the Bills training camp facility in suburban Rochester.

“It feels good to be back on a team and back to playing football.”

The 31-year-old Bush has reason to be upbeat some nine months since tearing his meniscus ligament in St. Louis. It happened while he was pushed out of bounds while returning a punt and lost his footing on the concrete before sliding into the padded wall of the stands.

“I thought my career could be over. Those were my initial thoughts,” he said.

Instead, Bush joins a Rex Ryan-coached, run-first-oriented offense that led the league in rushing last season, and a team with a hole to fill in its return game.

BUCCANEERS: Receiver Vincent Jackson is back on the practice field after missing a big part of last season because of injuries.

The three-time Pro Bowl selection is also excited about the upcoming release of a second children’s book he’s written to support military families.

“Danny Dogtags: Soccer Superhero” will go on sale next month, with proceeds supporting the player’s Jackson in Action 83 Foundation, which he launched four years ago to help military moms and dads remain connected with their kids during deployments, as well as heighten awareness of other issues facing service members and their loved ones.

CARDINALS: Coach Bruce Arians says wide receiver John Brown will be sidelined while undergoing the concussion protocol.

Brown was hurt when his head slammed into the turf during a collision with cornerback Patrick Peterson at Sunday’s practice.

Also, cornerback Mike Jenkins broke a bone in his right hand in practice on Saturday and, Arians said, was to undergo surgery Monday.
