The Kansas City Royals placed catcher Salvador Perez on the seven-day concussion list Monday.

Perez, 33, was removed from Saturday's game against Houston following a foul tip to the mask.

The eight-time All-Star is batting .252 with 21 homers and 72 RBIs in 133 games this season.

Kansas City called up Tyler Cropley from Triple-A Omaha and transferred fellow catcher Freddy Fermin to the 60-day injured list.
