No. 14: Ellsbury's lost season
When Jacoby Ellsbury broke five of his ribs during a collision with Adrian Beltre back on April 11, Red Sox fans didn't realize what an impact the injury would have on the speedy center fielder. Ellsbury returned to the field in June, but was back on the DL a few days later with another broken rib. On August 17, after breaking yet another rib in his return, Ellsbury was done for the season.
