Reyes was out of the lineup for Saturday night's game against Tampa Bay. Blue Jays manager John Gibbons said Reyes will also sit out Sunday's game with the Rays, but expects the leadoff hitter to return after an off-day Monday for a series with the New York Yankees that begins Tuesday.
"His knee is a little banged up," Gibbons said. "It's something that just kind of flared up on him. Give him three days. We don't think it's any big deal."
Reyes missed 66 games this season because of a left ankle injury. He is hitting .291.
Toronto is also minus infielder Munenori Kawasaki. He was put on the paternity list Friday for the birth of his son and Gibbons doesn't expect him back until Tuesday.
