Reynolds suffered the injury after being hit just above his left hand on a hard liner by Tampa Bay second baseman Sean Rodriguez in the fifth inning.
"Yeah, when it first happened it wasn't too bad, it was hurting just a little bit," Reynolds said of his forearm. "As the game went on, kind of sitting around, it started swelling up a lot. I couldn't really grip the bat very well, turn my wrist over, so I wasn't going to hurt the team by going out there and trying to hit when I couldn't."
The injury only added to a difficult game for Reynolds, who committed errors in the first and seventh innings. The 27-year-old has the most errors in the Majors with 14. He was 0-for-2 with a walk before departing.
