Nose tackle Ma'ake Kemoeatu has been placed on season-ending injured reserve due to a shoulder injury, the Redskins announced on Wednesday.

Kemoeatu has played most of the season with a sore shoulder. He has had it wrapped so that he could play in games.

The physicality of the nose tackle position took a toll on the shoulder as the season progressed.

"Throughout the year, the shoulder was running at 50 percent," he said. "I tried to do the best I could with it."

Kemoeatu played in 14 games with 12 starts for the Redskins this season.

He finished his first season in Washington with 40 tackles and five quarterback hurries.

Kemoeatu is uncertain if the shoulder injury is going to require surgery

"We'll find out next week," he said. "Doctors are going to look at it to see if I need surgery."

Kemoeatu signed with the Redskins last offseason after missing the entire 2009 season with an Achilles injury. He rehabbed the Achilles back into playing shape and then suffered the shoulder injury early this season.

"To miss a whole year of football and rehabbing to get back in shape, then before you know it the season starts, and right when you're back in shape you get another injury, it's frustrating sometimes," Kemoeatu said.

Asked if he would be able to come back for the 2011 season, Kemoeatu replied: "Definitely. I want to have a great offseason, so that I'm 100 percent and full speed before the season starts."

-- SAFETY A CONCERN

Safeties Reed Doughty and Kareem Moore did not practice on Wednesday.

Doughty continues to recover from a concussion and Moore has a knee injury.

Mike Shanahan said Doughty was "feeling much better," but his status for Sunday's game in Jacksonville is uncertain.

"We have to wait until the experts look at it," Shanahan said. "I am not sure if it will be Thursday or Friday until we know for sure."

If Doughty and Moore are unable to play, then that would leave the Redskins with just one healthy safety -- Macho Harris.

Shanahan said the team may have to sign another safety this week, possibly first-year player Sha'Reff Rashad from the practice squad.

"Yeah, it is a little tough," he said. "So we've got to find another guy to at least put in there."

Cornerback Kevin Barnes lined up at safety when Doughty was injured in last Sunday's game vs. Dallas.

-- NO PRACTICE FOR ORAKPO

Linebacker Brian Orakpo, still slowed by groin and hamstring injuries, sat out Wednesday's practice.

"His groin is still sore and the hamstring is a little bit better," head coach Mike Shanahan said.

Shanahan added that it was too soon to consider putting Orakpo on injured reserve.

Orakpo has played in every game since entering the league as the Redskins' 2009 first-round draft pick.

He leads the defense with 8.5 sacks.

-- GOLSTON UPDATE

Defensive end Kedric Golston's status for this week's game vs. Jacksonville does not look promising.

He did not practice on Wednesday due to groin and elbow injuries.

"I am not ruling him out, but it is a long shot right now," Mike Shanahan said.

Golston did not play in last Sunday's game vs. Dallas due to the injuries.
