College basketball player arrested, later beaten up in jail fight

This is what you call a bad night,.

Dayton basketball player Sam Miller's Sunday night was bad enough when he got arrested and taken into custody for underage drinking and disorderly conduct after being kicked out of a bar.

But it gets worse from there.

Miller reportedly urinated on the floor of his cell, which led to cellmate John Watkins Jr., slapping him after complaining about being lodged with the basketball player, according to a police report cited by Dayton Daily News.

Miller was charged with assault for his involvement in the incident and was taken to the local hospital shortly after, according to the Daily News report.

The University of Dayton acknowledged the incident, but couldn't issue a comment about the arrest or video.

"The University of Dayton is aware of an incident, but cannot discuss individual student matters because of federal privacy laws," Dayton Athletic Director Neil Sullivan said in a statement. "With all student conduct matters, the University responds in accordance with the University's Student Code of Conduct and other applicable standards."

According to the police report, as cited by the Daily News, Miller pushed a bartender and knocked glasses off of the bar before being cut off and thrown out. He has pleaded not guilty to both charges stemming from the bar and jail incidents.

Last season, Miller averaged 12.2 minutes per game, 4.5 points and 2.3 rebounds for Dayton last season.
