Seattle activated right tackle Abraham Lucas from injured reserve before the Seahawks' game Thursday night at the Dallas Cowboys.
In a corresponding move, Seattle (6-5) placed right guard Phil Haynes (toe) on injured reserve to make room on the 53-man roster.
Lucas went on IR after sustaining a knee injury in the season opener. He returned to practice two weeks ago and was a full participant this week.
"He's back to where we're counting on him to be able to help and contribute," coach Pete Carroll said Tuesday before the team left for Dallas. "... Abe had a good week. Everything's kind of on schedule as we planned it out quite some time ago aiming for this week. He did his part."
The Seahawks made Lucas, 25, a third-round selection in the 2022 NFL Draft out of Washington State. He started 16 games last season and this year's season opener, a 30-13 home loss to the Los Angeles Rams on Sept. 10.
Haynes, 28, missed practice this week because of the toe injury and was ruled out Wednesday for the game against the Cowboys (8-3). He will have to miss at least the next four games.
A fourth-round draft pick by the Seahawks in 2019, Haynes has played in eight games this season (all starts) and 31 total (13 starts) in five seasons.
The Seahawks also elevated wide receiver Cody Thompson from the practice squad on Thursday. Thompson, 27, has appeared in six games this season, primarily on special teams, and has one reception for 10 yards.
