The San Francisco 49ers expect to have starting right tackle Mike McGlinchey and fullback Kyle Juszczyk back in the lineup for tonight's game against the Seattle Seahawks. It sounds like both of those players assume that to be the case, according to their social media posts today.

McGlinchey is "back at it," he says, and Juszczyk is "back at work."

That's a significant boost for the undefeated 49ers, who are headed into a crucial division matchup and will likely be without Pro Bowl tight end George Kittle.

McGlinchey, a second-year starter, has missed time since suffering a knee injury during Week 5 against the Cleveland Browns. He was listed as "questionable" to play against the Seahawks.

McGlinchey started each game of his NFL career before that Week-5 injury.

Juszczyk started practicing last week after suffering an MCL sprain during Week 5. He too was listed as "questionable" entering tonight's game.

Juszczyk, a seven-year veteran, entered the league as a fourth-round draft pick by the Baltimore Ravens in 2013 and joined San Francisco in 2017. He has carried the football one time for six yards while adding six receptions for 76 yards through four starts this season, and his blocking ability is an important part of the team's run game.
