Reyes has been sidelined since April 27 with a fractured left rib suffered on a check swing in the fourth game of the season. He is batting .250 with no home runs and seven RBIs.
Reyes went 4-for-11 with two RBIs and scored twice during a three-game rehab stint with Buffalo that ended Saturday. He returned to Toronto on Sunday and was in the clubhouse following an 8-2 win over Seattle.
The four-time All-Star and 2011 NL batting champion is expected to return to the leadoff spot when Toronto begins a three-game series against the White Sox on Monday night.
