McGough was drafted by the Seahawks in the seventh round of last year's draft and spent the season on the team's practice squad. He'll now set his sights on making the Jaguars' roster in 2019.
The Seahawks signed McGough to their practice squad Monday, Bob Condotta of The Seattle Times reports.
McGough had a turbulent preseason, with moments of poise and others that revealed why no team selected him until the seventh round of April's draft. In turn, the Seahawks traded for Brett Hundley to be Russell Wilson's backup. McGough will use the time time to develop and possibly vie for the backup role in 2019 when Hundley's contract expires.
Seattle apparently wasn't too impressed with the backup quarterback battle between McGough and veteran Austin Davis. The rookie seventh-round pick at least still figures to have a spot on the practice squad, while Davis may just be out of a job. It is possible the team could carry three quarterbacks until Hundley has a strong knowledge of the playbook.
McGough completed nine of 12 passes for 97 yards and one touchdown in Saturday's 24-14 preseason loss to the Chargers.
McGough, who was selected in the seventh round of April's draft, is battling Austin Davis to be Russell Wilson's backup. Davis converted on just one of three tries for six yards Saturday. The difference in attempts and all around performance gives McGough a slight edge in the battle so far, but expect the competition to continue through the final preseason outing.
