Possibly in response to Josh McCown's concussion, the Browns brought a fourth quarterback to Berea.
Here's what the Browns' official website had to say about Matt Blanchard in their press release:
Blanchard is 6-3, 223 pounds and officially in his second NFL season out of Wisconsin-Whitewater. Originally signed by Chicago as an undrafted free agent in 2012, Blanchard has spent time on the practice squads in Chicago and Carolina. He spent training game this year with Green Bay and was waived during final roster cuts. In college, he guided the Warhawks to a 45-0 record and three Division III national championships during his three seasons after transferring from Northern Michigan.
