Redskins safety LaRon Landry will miss his fifth game of the season, and second straight, Sunday against the New England Patriots, this time because of a nagging groin problem.

Landry, who has also missed time because of problems with his Achilles tendon and hamstring, was unable to practice on Friday, the third straight day he had been out. Coach Mike Shanahan said he couldn’t predict whether Landry will be back for the Redskins’ final three games.

“Still don’t know,” Shanahan said. “He’s getting better.”

Also out for Sunday’s game is defensive lineman Chris Baker, who was elevated from the practice squad just this week. Baker strained a groin muscle in Wednesday’s practice.

Punter Sav Rocca, who rolled his left ankle when a New York Jets player ran into him in last week’s game, should be able to play, Shanahan said.

“He’s very tough-minded,” Shanahan said. “For him to go back in like he did with that type of ankle [injury], I was guessing that he would be ready to go just knowing how he operates, who he is.”

The Redskins worked out punter Ricky Schmitt on Thursday in case Rocca wasn’t ready.
