Cardinals C Shipley carted to locker room with injury
Shipley was able to walk off the field on his own but after a brief time in an examination tent was taken to the locker room on a cart, a towel draped over his head.
The six-year NFL veteran started all 16 games in each of the past two seasons.
There was no post-practice coach availability and the team has Sunday off so the extent of the injury might not be publicly known until the team resumes training camp on Monday.
Rookie Mason Cole, a third-round draft pick out of Michigan, replaced Shipley with the first unit following the injury.
