(CBS) The Bears will likely be still sorting through their receivers in New Orleans on Sunday, with Markus Wheaton doubtful to play after missing practice all week with a groin injury.

While Wheaton mended the injury suffered two weeks ago in practice, the Bears acquired receiver Dontrelle Inman in a trade with the Chargers this week. However, Inman only practiced Friday after arriving to Chicago late Wednesday night. If he does suit up against the Saints, it would likely be a limited role.

The Bears have listed defensive lineman Roy Robertson-Harris (hamstring), linebacker John Timu (ankle/knee) and cornerback Sherrick McManis (hamstring) as doubtful to play, while center Hroniss Grasu (hand) and running back Benny Cunningham (hamstring) are both questionable.

The Saints have yet to make a determination on top receiver Michael Thomas (knee), who missed practiced Wednesday and was limited in work Thursday.

Kickoff between the Bears (3-4) and Saints (4-2) comes at noon on Sunday from New Orleans.
