Red Sox southpaw Rich Hill done for season?

Red Sox left-hander Rich Hill will seek a second opinion on what reports are calling a very serious injury in his throwing elbow. Hill has struggled with his mechanics and command in recent years, but appeared to have found his niche as the lefty specialist out of the 'pen. He has allowed a run in eight innings and has struck out twelve to just three walks. 

One could easily watch Hill pitch and get uncomfortable by his delivery. He comes over the top with his body but will drop to three-quarters and sometimes sidearm-submarine depending on the pitch he is throwing. He worked hard to keep hitters uncomfortable, but only saw the success when two or more of his pitchers were effective. 

Now it looks like he will have a long road back to recovery, joining Daisuke Matsuzaka on the shelf for the next year or so. Can the Red Sox sustain any more injuries to its pitching staff?
