Colclough was arrested hours before becoming a casualty of the Panthers' final cuts. After spending five hours in the Mecklenburg County jail, Colclough was released Saturday afternoon on $1,000 bond.
"We're aware of it," team spokesman Charlie Dayton said of the arrest. He declined further comment.
The 26-year-old Colclough was signed by the Panthers in the offseason but failed to win the punt return and kickoff return jobs in the preseason. Dante Wesley and C.J. Wilson won the final cornerback spots on the team.
Colclough became the second Panther arrested on a DWI charge this year. Receiver Dwayne Jarrett pleaded guilty in June, three months after being pulled over in the Charlotte suburb of Mint Hill. Jarrett was ordered to pay court costs and perform 24 hours of community service.
Colclough was Pittsburgh's second-round pick in 2004. He played as a reserve and returned kickoffs in 30 games in his first two seasons with the Steelers, earning a Super Bowl ring after the 2005 season.
He spent most of the 2006 season on injured reserve with a neck injury and was inactive in 13 games in 2007 before Pittsburgh decided not to re-sign him.
