Former NFL defensive back Tommie Campbell was arrested Tuesday in Pennsylvania and charged with dozens of drug-related felony counts.

According to WPXI in Pittsburgh, police in Aliquippa, Pa., said they believe Campbell — who now plays for the Canadian Football League's Calgary Stampeders — was selling drugs out of his mother's house during the offseason.

Police obtained a search warrant for the house, the Beaver County Times reported, but as they arrived at the residence Monday night, Campbell attempted to flee by jumping over a fence in the backyard while carrying a backpack.

He apparently dropped the backpack, and police said it contained individually wrapped bags of crack cocaine and bundles of cash. A search of the home revealed more cocaine, in addition to scales and other drug paraphernalia, police said.

Campbell was eventually arrested Tuesday afternoon. According to the Times, he faces 21 counts each of possession of a controlled substance and possession with intent to deliver, plus 10 counts of possession of drug paraphernalia, one count of flight to avoid apprehension and one of tampering with evidence. All of the charges are felonies.

“He says he didn’t do it," Campbell's attorney Steve Colafella told WPXI. "He was quite frank about it with the court. He wants his name cleared.”

Campbell had 73 tackles and three interceptions in helping the Stampeders to the Grey Cup last season. He previously spent 2011-13 with the Tennessee Titans and 2014 with the Jacksonville Jaguars.
