ST. LOUIS � St. Louis Cardinals outfielder Rick Ankiel has been released from the hospital.

Ankiel was hospitalized overnight for observation after he slammed headfirst into the wall following a running catch Monday night.

He will rejoin the team before Tuesday night's game against the Phillies but won't play.

Ankiel chased down Pedro Feliz's long drive in the eighth inning against the Phillies but couldn't stop himself from crashing into the padded center-field wall. He took 2� off-balance steps after making the tough catch and took the ball out of his glove before attempting to brace himself with his left arm. Still, his head appeared to absorb most of the blow.

X-rays and a CT scan of Ankiel's head, neck and back showed no fractures.
