Francisco Cervelli bruises foot

TAMPA, Fla. -- Francisco Cervelli fouled a pitch off his left foot in the bottom of the second inning of Wednesday's Yankees-Astros game and left after three innings with a bruise.

Cervelli's foot was heavily wrapped and he was noticeably limping in the clubhouse after leaving the game.

"It's nothing bad, couple of days and that's it,'' he said "I wanted to continue but [manager Joe Girardi] said no. It's OK, it's just sore. It's a bruise, that's it.''

Cervelli suffered the injury in the course of drawing a second-inning walk. Girardi came out to the plate to check on him, and Cervelli went out to catch the top of the third inning before being replaced by Austin Romine.

Cervelli had a CT scan and an MRI on Wednesday. The CT was negative but the MRI was inconclusive and will be viewed by doctors. At minimum, Cervelli will not play Thursday or Friday, when Russell Martin will make his first start behind the plate.

Martin, signed in the offseason to be the starting catcher, has yet to catch a game due to lingering stiffness in his right knee, which was operated on for a meniscus tear just days after the Yankees signed him. Martin was seen wearing a knee brace in the clubhouse and is slated to be the designated hitter Thursday against the Rays in Port Charlotte, Fla.

If Cervelli is out any length of time, that leaves the Yankees with the inexperienced Romine and Jesus Montero at catcher, along with Jorge Posada, who was intended to be the full-time designated hitter this season but has participated in catching drills in case of emergency.

Cervelli is hitting well so far this spring, batting .600 (3-for-5) with a double and one RBI.
