Hurst (ankle) was placed on injured reserve Wednesday.
Hurst exited the Browns' Week 1 loss to the Cowboys with the injury, which will now put him out for at least the next four weeks. His absence will be a blow to the interior of Cleveland's defensive line, which the team will attempt to address with the signing of Sam Kamara from its practice squad. Although a specific return date for Hurst beyond the minimum of four weeks is unknown, according to Daniel Oyefusi of ESPN.com, head coach Kevin Stefanksi doesn't believe it's a season-ender for the Michigan product.
