CHARLOTTE, N.C. - The Carolina Panthers traded Todd Sauerbrun to the Denver Broncos Thursday, ridding themselves of their talented but troubled punter.

Denver sent punter Jason Baker and its seventh-round draft choice in 2006 to Carolina in exchange for Sauerbrun, a two-time Pro Bowl selection.

Considered by many to be the best punter in the NFL, Sauerbrun has created numerous headaches both on and off the field for the Panthers. Most recently, he was one of three players named in a CBS report as having obtained illegal steroid prescriptions from a South Carolina doctor under federal investigation.

He also was charged with drunken driving last season, not long after he refused to fill in for injured kicker John Kasay unless the Panthers refunded money they had fined him for being overweight.

USADA reduced the sanction to four years, and Collins agreed to drop her appeal.
