NORTH MANKATO, Minn. (AP) _ Former Minnesota Vikings great Carl Eller was released from jail Thursday while police investigated a sexual assault claims.

Police received a call at 1:55 a.m. Wednesday and arrested Eller.

He was released from jail Thursday pending further investigation. No other details were released and no charges have been filed.

Eller, 57, was a star defensive end with the Vikings' ``Purple People Eaters,'' which helped Minnesota to four NFC championships and Super Bowl appearances in the late 1960s and 1970s. Eller made six Pro Bowl appearances and was among 15 finalists for the Pro Football Hall of Fame this year.

He recently accepted a position with the Minnesota Department of Human Services as a policy analyst and spokesman on risky behavior, after spending nearly two decades as a drug and alcohol abuse counselor. He has opened three clinics over the years.

When Eller retired from football, he had to deal with his own drug and alcohol problems, which included cocaine addiction.
