Kalisto may be seriously injured after a fan threw a water bottle at his this past Tuesday.
He was injured this past Tuesday on WWE 205 Live. He was selling an assault from Jack Gallagher and Brian Kendrick when a fan off screen threw a water bottle and struck Kalisto. His wife Abigail Rodriguez on Twitter posted the following yesterday regarding the incident, saying that he required stitches (apparently on the upper lip, as the picture indicates), suffered a possible fracture and underwent an MRI:
WWE currently has not commented on Kalistos injury, and Kalisto hasn't posted on Twitter since the match.
Kalisto has been on the 205 Live roster for the last few months, serving as the first challenger to Enzo Amore's cruiserweight championship in the wake of Neville's departure from the promotion. Since the end of that feud, he has been teaming with Gran Metallik against Kendrick and Gallagher, which started off this week on 205 Live.
