Scheppers said he was "sucker-punched" by unknown assailants, who then fled the scene. Scheppers did not file a report with the Cleveland police, but they did take him back to his hotel. He suffered bruises and cuts around his left eye.
"I want to thank the Cleveland police for handling it properly and taking me back to the hotel," Scheppers said Monday. "The next time I'll be more careful."
Scheppers originally said he was alone when the altercation occurred. On Monday, he confirmed that Nathan and Pierzynski were with him.
"Initially, I didn't say it because I didn't think it was a big deal and I didn't want to involve them," Scheppers said.
