Missing the last two games with knee tendinitis, Redskins center Spencer Long returned to practice this week on a limited basis and enters Sunday's game as questionable.

This week's injury report is brought to you by Inova, the Official Health System of the Washington Redskins.

After ruling out five players before last Sunday's game against the Seattle Seahawks, the Washington Redskins head into Sunday's Week 10 matchup against the Minnesota Vikings with only defensive linemen Arthur Jones (shoulder dislocation) and Matt Ioannidis (hand) ruled out.

Tackles Trent Williams (knee), Morgan Moses (ankles) and Ty Nsekhe (core muscle), wide receivers Jamison Crowder (hamstring) and Brian Quick (concussion), tight ends Jordan Reed (hamstring) and Niles Paul (concussion), center Spencer Long (knees), guards Shawn Lauvao (stinger) and Brandon Scherff (knee), linebacker Zach Brown (ankle) and safety Montae Nicholson (shoulder) questionable for the game.

While the Redskins were without four of their starting offensive linemen during last week's victory over the Seahawks, Nsekhe, Lauvao, Long and Scherff all returned to practice on Wednesday with limited workloads while Williams practiced Friday for the first time in more than a month.

For Nsekhe, his potential return could allow Williams more time to recover from his knee injury depending on the five-time Pro Bowler's status. Nsekhe underwent core muscle surgery in late September and has been inactive for Washington's last five games.

As for Long, the fourth-year Nebraska product has missed the last two games with knee injuries. His presence back at center could be key in slowing one of the best defensive lines in the NFL today.

"They're very stout inside, very powerful," Long said. "They've got some got some good edge rushers on the outside and they're just a strong front all around. They've got depth as well, so we've just got to be ready to roll."

Lauvao and Scherff, meanwhile, have progressed in practices this week and are also among those listed as questionable.

Lauvao was removed from the Redskins' Week 8 loss to the Dallas Cowboys with a stinger and did not practice last week but returned for this week's sessions. While Scherff was active last week, the Pro Bowler did not appear in game action for a second consecutive game.

Depending on Long's health for Sunday's game along with the two starting guards, the Redskins could slide rookie Chase Roullier over from center to guard. Roullier started the past two games at center but has experience playing guard from his college days at Wyoming.

"The good thing is they've all been schooled at center/guard," said Redskins head coach Jay Gruden. "All those guys, Chase and Spencer. It looks like Lauvao had a decent day [on Wednesday]. He's on the upswing and Brandon's on the upswing, so hopefully we'll get a couple of those guys back. We'll wait and see."

Reed and Paul could also return to game action this week as neither tight end made the trip to Seattle after both were injured against the Cowboys.

While Vernon Davis has shined through eight games this season, catching 23 passes for 384 yards and one touchdown, Reed has been slowed by injuries in his six appearances this season, catching just 27 passes for 211 yards and two touchdowns. His 7.8 yards per reception is currently a career low as well.

Still, Reed can changes games when healthy.

Defensively, Ioannidis will miss another game after suffering a fractured hand against the Cowboys.

The second-year Temple product underwent a procedure recently to fix the injury but the question now is to what extent he can use his hand in football action once he does return.

"He's going to have it casted up and have his fingers free so he can still grab and stuff like that," Gruden said. "I think that's the important thing is can he grab without any pain and is it safe to grab right now so close to surgery? I think we want to make sure it's stable and he can do it without damaging it more."

As for Brown, he was an addition to the injury report on Thursday with an ankle injury. The Pro Bowl linebacker currently leads the NFL in tackles with 86, 10 more than any other player.

If the University of North Carolina product can't play on Sunday, the Redskins will look to Martrell Spaight and Josh Harvey-Clemons to pick up their production opposite Will Compton.
