Linebacker London Fletcher suffered a sprained left ankle during the Washington Redskins’ loss Sunday night to the New York Giants at FedEx Field. Coach Mike Shanahan provided no details Monday about the severity of Fletcher’s injury. It is not clear whether the injury will jeopardize Fletcher’s playing status for this weekend’s game against the Kansas City Chiefs. He has played in 252 straight regular season games. “I’ll let you know more on Wednesday exactly how serious that is,” Shanahan said. Tight end Niles Paul was back at Redskins Park on Monday after being absent from the team last week because he was sick, Shanahan said. Paul was on the inactive list for Sunday night’s loss. “He was in work this morning,” Shanahan said. “He’s feeling a little bit better.” Tight end Jordan Reed and safety Reed Doughty are subject to the NFL’s rules for treating players who suffer concussions and must be cleared by an independent neurologist to practice and play. Reed missed a second straight game Sunday night after suffering a recurrence of his concussion symptoms. He had said last week he’d expected to play against the Giants. Doughty suffered his second concussion of the season Sunday. “A guy has a second one, there is more concern,” Shanahan said.
