The Red Sox released a statement on Daisuke Matsuaka today. Here goes:
Daisuke experienced tightness in his elbow during his last start. His examination is consistent with a sprained ulnar collateral ligament, and strain to his common flexor mass. An MRI was obtained which confirmed these exam findings. He will be re-examined in two weeks.
Though the injury appears "manageable," expect Dice-K to sit at least a month. The likely replacement? The immortal Alfredo Aceves ... he of five career starts.
