The Boston Red Sox on Thursday issued a statement to update the status of outfielder Carl Crawford.

"Carl Crawford was examined by the Red Sox medical staff. He was diagnosed as having a left elbow ulnar collateral ligament sprain. A conservative treatment protocol was recommended. Carl was also examined by Dr. James Andrews who was in agreement with the assessment and plan. Carl received a Platelet Rich Plasma (PRP) injection and will be shut down from baseball activity during the initial phase of his treatment."

Crawford endured off-season surgery on his left wrist, but recovery from the procedure has kept him on the sidelines since spring training. He was placed on the 15-day DL in late March.

The 30-year-old hit .255 with 11 home runs, 29 doubles, seven triples and drove in 56 runs over 130 games for the BoSox last season.
