The Washington Redskins head into Sunday's game with Pro Bowl left tackle Trent Williams, who did not practice on Friday, among those questionable, while Kendall Reyes and Martrell Spaight are out.

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

The Washington Redskins will be without two defensive players for Sunday's game against the Dallas Cowboys, as defensive end Kendall Reyes (groin) and linebacker Martrell Spaight (concussion) have been ruled out.

Reyes has been dealing with the groin issue for the past two weeks and did not practice on Thursday and Friday.

In his absence, the Redskins will incorporate Cullen Jenkins and Anthony Lanier II into the defensive line rotation. Jenkins was signed back to the active roster this week after a short preseason stint, while Lanier was inactive for Washington's game against the Pittsburgh Steelers.

Spaight, meanwhile, was a new addition to the injury report on Friday, as he did not practice after feeling some dizziness.

The second-year Arkansas product missed 15 games last season after suffering a concussion in the season opener.

"There's a level of concern there," Redskins head coach Jay Gruden said. "We don't know to what extent yet, he's still going through all the tests and all that stuff. He just had some issues that we had to get checked out and we don't know when it occurred. It wasn't in practice, it just came up. He had a little dizziness …so we had to make sure we took care of him and make sure we did right and sent him to all the right people."

Defensive end Chris Baker (rib/elbow), tackle Trent Williams (glute), wide receiver Josh Doctson (Achilles) and safety Su'a Cravens (hip) are all listed as questionable for Sunday's game against the Dallas Cowboys at FedExField.

Baker was limited throughout practice this week as he dealt with rib and elbow issues.

The fifth-year Hampton product appeared in 50 of the defensive unit's 68 plays Monday night against the Pittsburgh Steelers.

Hopeful to appear in his 23rd consecutive regular season game for the Redskins, Baker doesn't want to miss the chance to play against Washington's archrival.

"I remember growing up watching the Cowboys-Redskins games, It was always a big game in my house," Baker said. "We understand at the end of the day, it's a divisional game. You can lose a lot of non-divisional games, but if you win the division, you have the chance to get a home playoff game and get into the playoffs. This a division game, so we've got to come out here and win this one."

Williams was a new addition to the injury report on Thursday as a limited participant before not participating in Friday's practice session.

Gruden said Williams will be assessed on Saturday before the team makes a decision on his playing status.

If Williams is unable to go on Sunday, 30-year-old Ty Nsekhe is listed as the No. 2 left tackle on the team's unofficial depth chart.

The Texas State product appeared in 13 games last season with two starts. In the Redskins' most recent game against the Cowboys – a 34-23 victory on Jan. 3 at AT&T Stadium – Nsekhe started and held former Cowboys defensive end Greg Hardy to zero sacks despite the latter having a contract incentive.

Despite only having a handful of practices in months last week, Doctson was active and appeared on 12 of the Redskins' 58 offensive plays.

The Redskins' first-round pick in the 2016 NFL Draft recorded the first catch of his professional career in the fourth quarter of Monday's loss, a nine-yard gain.

The key for Doctson moving forward will be managing the aches and pains that come with an Achilles injury.

"He's still getting better and better and stronger and more comfortable," Redskins head coach Jay Gruden said. "He'll get more and more reps as we go on."

Linebacker Terence Garvin did not practice on Thursday with illness, but was back at the Inova Sports Performance Center at Redskins Park in Loudoun County, Va., on Friday.

For the Cowboys, linebacker Mark Nzeocha (Achilles), quarterback Tony Romo (back) and defensive end Charles Tapper all did not participate in practices prior to Friday.

Cornerback Orlando Scandrick (hamstring) appeared on the injury report starting Thursday with a hamstring issue and did not practice that day.

The nine-year veteran started last week's game against the New York Giants, recording three tackles and a fumble forced.
