Beckett questionable for April 7?

Boston Red Sox starter Josh Beckett is headed to San Antonio to have a thumb injury examined, the team confirmed Monday morning, and is questionable to make his first start of the season in Detroit on April 7. According to reports, Alfredo Aceves said he was told to be prepared to make that start and the home opener on April 13 in case Beckett is not available.

Aceves was informed Sunday that he was the odd man out in the race for the final two spots in the rotation, losing out to Felix Doubront and Daniel Bard. Now, it appears he could be making starts after all, depending on the prognosis on Beckett.

Beckett threw a controlled bullpen session on Sunday and his thumb injury was not mentioned as an issue.

Beckett’s thumb injury is the second one to hit the Red Sox pitching staff in the past two days. Closer Andrew Bailey might miss the start of the regular season with a thumb injury of his own.

Red Sox manager Bobby Valentine is schedule to address reporters on Beckett around 11 a.m.
