Jeffcoat (hamstring) was placed on the Browns' PUP list Friday, Dan Labbe of cleveland.com reports.
Jeffcoat is reportedly nursing an injured hamstring that he suffered during Thursday's team conditioning test. Entering his third season in the league, Jeffcoat figures to serve as a depth linebacker for a Browns team that added the likes of Demario Davis and Joe Schobert to the linebacking corps this offseason. In his first two seasons, Jeffcoat has recorded six tackles in nine career games.
Redskins defensive end Jason Hatcher has missed practice all week and is listed as doubtful for Sunday's game against the Cowboys. Hatcher has missed Washington's last two games with a knee injury.

Robert Griffin III (shoulder), Bashaud Breeland (thigh), Barry Coefield (shoulder), Tom Compton (knee), Will Compton (shoulder), Jackson Jeffcoat (calf), Kory Lichtensteiger (stinger) and Darrel Young (ankle) are all considered probable.
