Cominsky suffered an ankle sprain during Sunday's loss to the Seahawks, William McFadden of the Falcons' official site reports.
EDGE Analysis
The good news for Cominsky is that the Falcons have a bye next week, and coach Dan Quinn said he's "hopeful" the rookie defensive lineman will be able to play in Week 10 at New Orleans. The 23-year-old has six tackles (two solo) while serving in a rotational role through his first eight games.
