McMillan secured both targets for 23 yards in the Buccaneers' 17-14 preseason win over the Bengals on Saturday night.
McMillan was able to carry over some of the momentum from his strong training camp performances, recording both his grabs just one play apart during the Buccaneers' second possession. The rookie has been pushing Trey Palmer for the No. 3 receiver job with his work in camp, and the battle could go straight through Tampa Bay's three preseason contests.
