66 Jordan Simmons G

The Seahawks extended a tender to Simmons on Wednesday, John Boyle of the team's official site reports.

Simmons started the first three games of his NFL career with the Seahawks last season after being claimed off waivers from Oakland, and impressed during that limited stretch. He sustained a season-ending knee injury during a Week 17 win over the 49ers, but is expected to recover before the start of training camp. With J.R. Sweezy having landed with the Cardinals, Simmons has a realistic shot at a starting role 2019.

Simmons (knee) was placed on injured reserve Tuesday, John Boyle of Seahawks.com reports.

The knee injury Simmons sustained during Sunday's game against the 49ers has proven to be more than just a first-degree sprain, ultimately becoming severe enough to land the offensive guard on IR for the remainder of the season. Seattle could be thin at the position if D.J. Fluker is unable to return from a hamstring injury in Week 16 against the Chiefs.

Coach Pete Carroll said Monday that Simmons' knee injury is "going to be an issue", John Boyle of the Seahawks' official site reports.

Simmons -- who injured his knee in Sunday's tilt with the 49ers -- was originally thought to have a first-degree knee sprain. However, Carroll indicated that the injury is more severe, and while the exact diagnosis is still unknown, it's likely Simmons will miss the remainder of the regular season. There's a chance D.J. Fluker (hamstring) returns for Sunday's game against the Chiefs, otherwise Ethan Pocic would likely fill in.

The team believes Simmons has a first-degree knee sprain, Curtis Crabtree of Sports Radio 950 KJR Seattle reports.

A first-degree sprain would indicate the least severe damage to one of the knee ligaments. Nevertheless, Simmons is likely to miss at least a week while recovering. Crabtree surmised in the same Twitter thread that D.J. Fluker (hamstring) at least has a chance to return for Week 16 against the Chiefs, but if both players are unable to go, Ethan Pocic would probably draw the start.

Simmons is questionable to return to Sunday's game against the 49ers with a knee injury, Brady Henderson of ESPN.com reports.

Simmons got the start at right guard in lieu of D.J. Fluker (hamstring), so that leaves the Seahawks precariously thin at the position. Ethan Pocic is now in the game for Simmons.
