Moss left Sunday's 41-38 overtime loss to the Ravens late in the fourth quarter with a right ankle injury, Jay Morrison of SI.com reports.
The running back gained 24 yards on nine carries and added 28 receiving yards on three catches (four targets) before limping off the field under his own power, and while Moss wasn't officially ruled out, he didn't get a touch in overtime. Should the injury prove to be serious, Chase Brown -- who led the Cincinnati backfield with 12 carries for 46 yards Sunday -- would be in line for a big role Week 6 against the Giants.
