"That got him pretty good," Rays manager Joe Maddon said. "First one hit him and we were concerned. And the second one definitely took him to the canvas. ... He was visably not doing too good."
Brandon Gomes was pitching to Rusney Castillo with two outs in the fourth inning of the Rays-Red Sox contest when Castillo fouled one of Gomes' offerings into Casali's mask. The foul ball that forced Casali out of the game was the second he took to the catcher's mask in the at-bat.
Casali went down behind home plate and was quickly joined by a Rays trainer and Maddon. After they talked briefly with Casali, they ushered him away from the field.
Veteran receiver Jose Molina came took over behind the plate.
