The Raiders defensive line has some question marks heading into Sunday's game against the Atlanta Falcons with defensive tackles Richard Seymour and Tommy Kelly were either limited or did not practice on Thursday.

Seymour was limited in practice for the second straight day as he continues to deal with a knee injury. Limited practice is nothing new for Seymour as the knee injury has caused him to either be limited or miss practice all season. After being limited in practice on Wednesday with a foot injury, Kelly did not practice on Thursday. Kelly has started every game for Oakland since the beginning of the 2008 season. Shawntae Spencer did not practice on Wednesday and looks in line to miss his third straight game.

While the defense has some question marks, the Raiders offense appears to be close to healthy. Running back Darren McFadden was a full participant for the second straight day, as was Darrius Heyward-Bey. Heyward-Bey missed Oakland's last game with a concussion he suffered in Week 3. Both McFadden and Heyward-Bey appear ready to assume their normal workloads against the Falcons.
