McMillan (knee) is listed as questionable for Sunday's game against the Browns.
Despite being listed as a full participant on all three Week 2 injury reports, McMillan isn't in the clear to make his season debut, which ultimately may not be known until about 90 minutes before Sunday's 1:00 p.m. ET kickoff. He's been dealing with a knee issue since early August, but if he's active this weekend, he'd join Ted Hurst and Tez Johnson as the WR options behind Emeka Egbuka and Chris Godwin.
