Saskatchewan Roughriders defensive end Odell Willis has been charged with driving under the influence in the U.S.

The team revealed Thursday that Willis was arrested Sunday in Atlanta.

"We have spoken with Odell and are gathering as much information as possible into the incident," Riders general manager Brendan Taman said in a statement.

"Odell and the Roughrider organization are taking this matter very seriously and we won't comment any further until the legal process has run its course."

The Riders picked up Willis in a trade with the Winnipeg Blue Bombers last month.
