The Seahawks added a third quarterback to their roster on Thursday, signing Jake Luton, a Marysville-Pilchuck High School graduate who was a sixth-round pick in the 2020 draft.

Tackle Cedric Ogbuehi, who has been dealing with a bicep injury, was placed on injured reserve to make room on the 53-man roster. Ogbuehi, who started four games at right tackle last season, will be eligible to return after three games.

Luton, who began his college career at Idaho, transferred to Oregon State after a stop at Ventura Community College. He was granted a sixth year of eligibility in 2019 because of a thoracic spine fracture sustained in a game at WSU in 2018, and he used that extra year to solidify his status as an NFL prospect, throwing 28 touchdowns with just three interceptions on his way to winning the Mayo Clinic Comeback Player of the Year Award.

As a rookie, Luton started three games for the Jaguars, completing 60 of 110 pass attempts for 624 yards, two touchdowns and six interceptions.

In addition to those moves on the 53-man roster, the Seahawks also signed cornerback Michael Jackson to their practice squad. Jackson, a fifth-round pick of the Cowboys in 2019, started his rookie season on Dallas' practices quad, then was signed to Detroit's active roster in October. He was traded to New England last summer, released prior to the start of the season, then signed to the Patriots' practice squad. Jackson was released on Tuesday as part of New England's roster cuts.

Jackson played his college football at Miami, starting 23 of 51 games played over four seasons and recording 97 tackles, four interceptions, 11 passes defensed and 3.5 sacks. He earned All-ACC Honorable Mention honors as a senior, starting all 13 games and registering 42 tackles, six passes defensed and 2.5 sacks.

The Seahawks currently have two open spots on their practice squad.
