Uehara will be placed on the disabled list with a non-displaced distal radius fracture in his right wrist and is expected to make a full recovery.
Against the Tigers in Detroit on Friday night, Uehara was hit on the wrist by a line drive. He remained in the game to convert his 25th save and x-rays taken after the game were negative, but Uehara was sent back to Boston over the weekend for a complete examination including a CAT scan on Sunday.
Over 43 appearances this season, Uehara posted a 2.23 ERA with 25 saves and 0.917 WHIP.
The Red Sox now have two bullpen spots to fill after Justin Masterson was designated for assignment on Sunday. Replacement moves are expected to be announced before Tuesday’s game against the Miami Marlins; manager John Farrell said newly acquired Jean Machi would pitch as the closer without Uehara.
