Browns head coach Todd Monken said Wednesday that Hickman is in concussion protocol, Daniel Oyefusi of ESPN.com reports.
Hickman suffered a concussion in Week 9 against the Saints. He will have multiple steps to work through, but has the full week to clear concussion protocol. The fourth-year pro has 57 tackles (26 solo), four pass deflections and one interception in nine regular-season games this season.
