An MRI has revealed that Atlanta Braves center fielder Michael Bourn has sustained a sprained left thumb, reports David O’Brien of the Atlanta Journal-Constitution:

"I wanted to play as soon as I can, but I knew the day after (injuring it), it was too sore," Bourn said. "It swelled up the day after. But now most of the swelling’s gone. Some of the soreness is gone and it’s starting to feel better, but they just didn’t want me to rush out there and have any setbacks, which I can understand."

Bourn last appeared for the Braves on Saturday during the club’s contest against the Philadelphia Phillies. It was then that the 29-year-old sustained his injury, sliding head-first into first base.

Since the Braves have wrapped up the first National League Wild Card, they are unlikely to rush Bourn back into action. The MRI confirmed that there’s no ligament damage, and Atlanta is currently listing him as day-to-day.

Prior to his injury, Bourn had hit .274/.346/.391 with 25 doubles, 10 triples and nine home runs over 614 at-bats this season.
