Washington can’t catch a break with its offensive line. It announced Thursday it has placed tackle T.J. Clemmings on injured reserve. Clemmings’ ankle injury ended his season after he appeared in six games. Washington claimed him off waivers from the Vikings to become the team’s fourth offensive tackle, but he had to start the past two games at left tackle with Trent Williams (knee) and Ty Nsekhe (core muscle) still out.
