Josh Beckett, diagnosed wild mild concussion symptoms on Monday after being struck in the head by a ball during batting practice, passed the tests administered Wednesday morning but will be held out of his scheduled start Thursday against the Phillies. Minor-leaguer Stolmy Pimentel will replace Beckett.
"He passed his test, which means he's allowed to do some activity. Now again, they have to monitor his activity," said Red Sox manager Terry Francona. "He'll do some biking and some light throwing and then we'll see how he progresses from there."
Beckett told WEEI.com that he felt better on Wednesday, while Francona said that the pitcher should be ready for his next scheduled start in four days. "The No. 1 thing is to make sure he's OK and he tolerates his activity. He's only missed one day of throwing. We'll see where he's at."
