Reyes was placed on the 10-day injured list Monday with left elbow inflammation, Ian Browne of MLB.com reports.
Reyes played through an elbow issue in Sunday's 7-4 loss to the Dodgers after the injury prompted his early exit from Saturday's 8-5 victory over Los Angeles. He may have suffered a setback in his return to action and will now be on the mend for at least the next week and a half. The Red Sox called up David Hamilton from Triple-A Worcester to add depth in the middle infield, but Luis Urias will likely get the first chance to replace Reyes as Boston's primary second baseman.
