Brown was declared out for the game on Friday by head coach Mike Shanahan.
“It’s still sore,” Shanahan said of Brown’s injury.
Brown suffered the injury during pre-game warm-ups of last Sunday’s game against the New England Patriots.
Polumbus, a 6-8, 300-pound offensive lineman, earned Shanahan’s confidence by stepping in for Brown at the last minute vs. New England.
On Sunday at MetLife Stadium, Polumbus matches up against defensive end Justin Tuck, who has eight sacks and four forced fumbles in 11 career games against Washington.
“You always feel more confident about a guy after he’s played for a week,” Shanahan said. “And he did a good job for us, so we expect him to play well. He has to play well because they have an excellent defensive front.”
Polumbus, a four-year veteran, also saw action at left guard earlier this year. He joined the club on Nov. 9.
“Tyler has been getting reps at all the positions, knowing that he would have to be a swing guy,” offensive coordinator Kyle Shanahan said. “I thought given the situation he was in, he stepped in and helped us.”
As for left tackle, Mike Shanahan declined to name a starter for the second week in a row.
He said that both
Locklear, a 7-year veteran, started vs. New England and rotated with Smith until early in the second quarter when coaches opted to play Smith the rest of the game.
Locklear and Smith match up against Giants defensive end Jason Pierre-Paul, an explosive pass rusher who has 12.5 sacks this season. Who plays could depend on how they fare early on against Pierre-Paul.
“Both guys will get a chance to play,” Shanahan said. “I’m happy with both guys.”
