Backup quarterback Tim Tebow could see time at running back in the New York Jets' banged-up backfield Sunday against the New England Patriots.

"That's a possibility," coach Rex Ryan said Thursday. "The thing about Tim -- with him being a football player like we've always talked about -- by playing quarterback, he knows all the positions. So, can you plug him in at running back? Can you plug him in at tight end or whatever?

"I think the answer is yes."

The Jets are a bit short-handed at running back with backups Joe McKnight (sprained left ankle) and Bilal Powell (separated right shoulder) likely out for the game -- although McKnight insisted, "It's for first place, I'm in there."

That leaves only starter Shonn Greene and rookie Jonathan Grimes, who has yet to play, as the team's only completely healthy running backs.

Offensive coordinator Tony Sparano echoed Ryan's comments on Tebow and was just as vague.

"There's a possibility," he said. "There's a possibility for a lot of things. We'll see."

Tebow's role has been limited in his first season with the Jets, but he has carried the ball 18 times for 64 yards -- all on direct snaps as the team's wildcat quarterback or in the read-option package. He has lined up at quarterback, tight end, wide receiver, fullback and running back at times.

Reid's son: An accidental heroin overdose killed Garrett Reid, the son of Philadelphia Eagles coach Andy Reid, a coroner in Easton, Pa., said.

Coroner Zachary Lysek said a toxicology test confirmed the presence of heroin in Garrett Reid's body. Investigators revealed they found a used syringe and spoon in his room, along with a gym bag filled with dozens of syringes and needles, many of them unopened.

"We are confident today that Mr. Reid's death was the result of a self-injected lethal dose of heroin," District Attorney John Morganelli said at a news conference.
