Falcons cut veteran center Hawley, pick up Gradkowski
Hawley, slowed by his recovery from surgery on his right knee, played a backup role in Atlanta's final preseason game against Baltimore.
The team signed eight players, including quarterback Matt Simms, to its practice squad. Linebacker Stansly Maponga, Atlanta's fifth-round pick in 2013, and 2014 seventh-round pick Tyler Starr also were signed to the practice squad after being waived on Saturday.
