Cards' Ben Patrick out 'a few weeks'

FLAGSTAFF, Ariz. -- Arizona Cardinals tight end Ben Patrick displaced his left kneecap in a Wednesday night practice, an injury that coaches initially thought would be much worse.

Coach Ken Whisenhunt says the kneecap is back in place but Patrick will be sidelined for "a few weeks." The coach says he expects Patrick to be ready to play when the regular season begins on Sept. 12.

Patrick was hurt when he caught a short pass over the middle and was knocked down from behind by cornerback Greg Toler in an often-intense workout under the lights at a local high school. He was helped off the field and later was seen limping along the sidelines, able to put some weight on the injured knee.

Whisenhunt says he does not expect to add a tight end to the roster during Patrick's absence.
