Deablo (forearm) has been ruled out for Sunday's game against the 49ers, Will McFadden of the Falcons' official site reports.
Deablo was held out of practice all week due to a forearm injury that he picked up in a Week 6 loss to Chicago. Harold Perkins and Josh Woods figure to be the top candidates to start alongside Kendal Daniels (neck) at inside linebacker in the absence of Deablo, whose next chance to play is Week 8 against Tampa Bay on Sunday, Nov. 1.
