The Atlanta Falcons activated safety William Moore from the injured reserve list on Friday.

Moore had been on injured reserve with designation to return since Week 4 with a right shoulder separation. He practiced this week and could be cleared to play Sunday against the Arizona Cardinals.

The 6-foot, 221-pound Moore was selected by the Falcons in the second round (55th overall) of the 2009 draft. In four-plus seasons as a starter, Moore has amassed 421 tackles with 3.5 sacks, 14 interceptions and nine forced fumbles.

The Falcons also waived tackle Cameron Bradfield.

Bradfield (6-4, 308 pounds) was originally signed by the Jacksonville Jaguars as a college free agent out of Grand Valley State following the 2011 draft. He was signed by the Falcons on Sept. 30.
