Reports this morning out of Detroit have Lions running back Reggie Bush not practicing Friday, with his right leg wrapped up. Bush hasn’t been listed on the Lions’ injury report this week.

If Bush can’t play Sunday against the Dallas Cowboys, that would very much please owner Jerry Jones.

Jones was asked Friday morning on KRLD-FM who he’s more worried about this week with the Lions: wide receiver Calvin Johnson or Bush.

“Well, I think Bush,” Jones said. “When I look at where we seem to have some vulnerability using the passes out of the backfield, I look at what San Diego did, I look at times what Philadelphia did, if they were able to do anything at all, coming out of that backfield. That seems defensively to be a rough area for us.
