Corey Coleman will make his Buffalo Bills preseason debut Friday versus his former club, the Cleveland Browns, even though the wideout is still grasping his new team's offense, head coach Sean McDermott said Wednesday.

"We're getting to the point now where it's, 'Hey, here's the playbook, you got to know it,'" McDermott told reporters, according to ESPN's Mike Rodak. "Right now we're still digesting. ... There will be some clarity around what his role is Friday night. Biggest thing is we want him to come out and play fast and play physical."

The Bills acquired Coleman in a trade with the Browns on Aug. 5, giving the former first-round pick a chance to ignite his career after two underwhelming seasons in Cleveland. It was revealed Tuesday night on HBO's "Hard Knocks" that Coleman essentially asked the Browns to trade him after learning he was in line for a reduced role.

Bills general manager Brandon Beane said upon landing Coleman that the 24-year-old would have to earn a roster spot, let alone a prominent role in Buffalo's offense. It took just a seventh-round draft pick in 2020 for the Bills to poach Coleman from Cleveland.

Coleman had 56 catches for 718 yards and five touchdowns in 19 games across two seasons with the Browns.
