McMillan (knee) was on the field running routes at Monday's practice, PewterReport.com reports.
Both McMillan and Emeka Egbuka (toe) were participating in Monday's session, putting both in good position to play Sunday against the Bengals. McMillan missed most of training camp, but his injury never sounded serious. He's expected to compete with rookie Ted Hurst for WR3 duties behind Egbuka and Chris Godwin this season. McMillan is the favorite to open the campaign in three-wide sets.
