Manager Terry Francona said that Lowell's right eye was "twitching" but that he seemed fine otherwise after the incident in the fifth inning of Boston's 10-8 win over the Yankees. Lowell was removed for precautionary reasons.
"He's OK. He's a little bit sore," Francona said. "The ball hit him in the temple. … I'm sure that his jaw will be a little sore tomorrow."
Lowell was not in the Red Sox' clubhouse after the game. He managed to finish the inning after being hit but was removed to start the bottom of the sixth and replaced by rookie Lars Anderson.
