12:55pm: The Panthers’ deal with Gradkowski is now official.
A Delaware product, Gradkowski has appeared in 44 games during the course of his four-year career, and was a full-time starter for the Ravens during the 2013 season. He wasn’t very productive that year, grading as the worst center in the league, according to Pro Football Focus (subscription required). Last year, Gradkowski appeared in four games (one start) for Atlanta.
The Falcons added one of the league’s top centers in Alex Mack on Wednesday and soon after it was reported that they would not retain Gradkowski.
