You may remember not seeing Baron Corbin vs Kalisto at Summerslam at all, and the reasoning is because Kalisto is injured and there was something also about timing issues. Kalisto did wrestle on the August 2nd episode of Smackdown, losing the Intercontinental #1 Contenders match to Apollo Crews. Baron was in the match also, though. There is not any word yet on Kalisto's injury, but he did have to be helped to the back after the match ended.

In case you missed that match, below is a YouTube video that WWE uploaded.
