MINNEAPOLIS — Authorities say that four Minnesota football players who have been suspended for the last three weeks will not face any charges stemming from an alleged sexual assault.

The Hennepin County Attorney's office released a statement on Monday saying there was insufficient evidence to prove an assault occurred.

Cornerbacks KiAnte Hardin and Ray Buford, safety Dior Johnson and defensive end Tamarion Johnson were suspended after the first game of the season while police investigated to find out if they had any involvement in the alleged incident.

The university has not commented yet on the decision.

The Gophers host Iowa on Saturday.
