NFL.com reports that fullback Ovie Mughelli is likely out Sunday night vs the Bears:

It looks more and more as if the Falcons will not have starting FB Ovie Mughelli for Sunday night’s home game against the Bears. Mughelli missed his second day of practice Thursday because of a left calf injury, and his return to practice Friday is questionable, Falcons coach Mike Smith said. Mughelli, the lead blocker for RB Michael Turner, sported a walking book in the locker room and walked with a significant limp.
