Roberts hobbled by foul ball; X-rays negative

CHICAGO -- Brian Roberts was sore and limping after fouling a ball off his right kneecap during the Yankees' 6-5 loss to the White Sox on Friday, but X-rays taken at U.S. Cellular Field were negative and the infielder said that he expects to be available to play on Saturday.

Roberts injured himself during a fourth-inning at-bat against Hector Noesi, hobbling around the plate after clipping his knee with a foul ball. Roberts stayed in the game until he was replaced by Brendan Ryan for defense in the ninth inning, finishing the night 1-for-4 with a run scored.

"I told [manager Joe Girardi] I could finish, but I think it just got to the point where you've got one inning left," Roberts said. "It got pretty stiff, pushing off, slowing down running, stuff like that. The cooler weather didn't help either."

Roberts is batting .232 (32-for-138) with one home run and nine RBIs in 41 games this season, his first with the Yankees. Girardi said that he was not certain if Roberts would be in his lineup on Saturday against the White Sox.

"I don't know what we'll have tomorrow in him, so we'll have to wait and see," Girardi said.
