PHILADELPHIA -

Phillies all-star outfielder Domonic Brown has been placed on the 7-day disabled list due to concussion symptoms. Lehigh Valley's Steve Susdorf has earned the promotion to the big leagues.

The move comes after Brown hit his head hard on the ground trying to make a diving catch in Tuesday's game at St. Louis. Brown was shaken up so much that he sat out Wednesday's game before being placed on the DL Thursday.

Steve Susdorf gets the call up to the Phillies. Susdorf, a career minor league player, is having an outstanding season with the IronPigs, hitting .335.
