Red Sox second baseman Dustin Pedroia said he is "not sure" whether he will play baseball again because of his chronically injured left knee.

Pedroia discussed his injury at Fenway Park on Monday, shortly after the Red Sox transferred him to the 60-day injured list.

Flanked by manager Alex Cora and president of baseball operations Dave Dombrowski, Pedroia said he will shut down his recovery indefinitely in order to ponder his future.
