Allen Park ó Donít worry: Reggie Bush said he is playing Sunday against the Cowboys.
The Lions running back walked around the indoor practice field Friday with an ice pack on his upper right leg and didn't practice, but Bush said he was just taking a day off.
"I'm playing Sunday," he said. "That's all you guys need to know."
He also briefly explained why he was wearing the ice pack on a body part not yet known to be injured.
"I ice everything," he said. "If it needs ice, I put it on there."
Lions coach Jim Schwartz wouldn't shed any light on what kept Bush out Friday, but said that players who practice Wednesday and Thursday are typically available for games.
"If we have guys that don't practice on Wednesday and Thursday, most of them are injury related," Schwartz said.
The Lions injury report with game designations comes out at 4 p.m.
Rookie Theo Riddick was working in Bush's place during the skeleton drills.
Right tackle Corey Hilliard (knee) has not practiced all week and likely will be designated as out for Sunday.
Tight end Brandon Pettigrew (hamstring), receiver Calvin Johnson (knee), left tackle Riley Reiff (hamstring), defensive tackle Andre Fluellen (concussion), cornerback Rashean Mathis (groin) and linebacker Ashlee Palmer (ankle), all listed as limited Thursday, practiced on Friday.
