The Seahawks added interior line depth Tuesday, signing defensive tackle P.J. Johnson.
Johnson, a seventh-round pick by the Detroit Lions in 2019, spent his rookie season on the Chargers' practice squad after being cut by the Lions. The Chargers signed the 6-foot-3, 335-pound Johnson to a reserve/future contract after the 2019 season, then waived him earlier this month.
Johnson began his college career at Sacramento State, then transferred to City College of San Francisco before finishing his college career at the University of Arizona. During his one season at Arizona, Johnson played 10 games, starting nine, and was an All-Pac-12 honorable mention selection after recording 31 tackles, 8.5 tackles for loss and 3.0 sacks.
This move, along with the waiving of defensive end Marcus Webb over the weekend, leaves the Seahawks with 79 players on their roster.
