Blue Jays shortstop Jose Reyes had to be carted off the field during Friday night's series opener after injuring his left ankle while stealing second base against the Royals.
Reyes was diagnosed with a sprain and was taken to a hospital for an MRI.
Shortly after delivering a two-run single in the sixth inning, Reyes made a break for second and looked back as he was nearing the bag. He went into a late, awkward slide with his right foot forward and dragged his left foot over the bag before being called safe.
Reyes was in obvious pain as Blue Jays medical officials tended to him. He pulled his shirt over his face as his leg and ankle were stabilized.
Early word is that Reyes could be facing a stint on the disabled list of one to three months.
Reyes entered Friday's game hitting .412 and has reached base in all 10 of Toronto's games.
