Pitts (hamstring) has been ruled out for Sunday's game against the Buccaneers, Michael Rothstein of ESPN.com reports.
Pitts has missed three consecutive practices due to a hamstring injury, and the question now becomes whether he'll manage to recover in time for Week 6 versus the 49ers. Parker Hesse and Anthony Firkser will work to pick up the slack at tight end versus Tampa Bay on Sunday, but fantasy managers in need of a replacement for Pitts could have better luck perusing the waiver wire than Atlanta's positional depth chart.
