The Seahawks signed three players to their practice squad on Thursday, including quarterback Sean Mannion, who spent training camp with the team last season.
Also signing were tackle Jalen McKenzie and cornerback Xavier Crawford.
Mannion, a 2015 third-round pick out of Oregon State, spent his first four seasons with the Rams, including time working with current Seahawks offensive coordinator Shane Waldron, then later joined the Vikings before joining the Seahawks for training camp last season. He re-joined the Vikings last season after being released by the Seahawks.
"Sean is probably going to end up being a head coach in this league at some point," general manager John Schneider said. "… He's a guy that is like another coach in the room for Geno (Smith) and Drew (Lock)."
McKenzie, an undrafted rookie out of USC, signed with Tennessee following the draft, and was waived as part of this week's roster cuts. He is the son on longtime NFL executive and former Raiders general manager Reggie McKenzie, with whom Schneider worked in Green Bay. His older brother, Kahlil, has also spent time with the Seahawks.
"I actually held (McKenzie) in my arms as a baby a number of years ago," Schneider said. "Now he's like 6-6, 320 pounds, so I probably won't be doing that anymore."
Crawford, a 2019 sixth-round pick of the Texans in 2019, spent most of the past three seasons in Chicago where he was coached by current Seahawks associate head coach-defense Sean Desai. Crawford has played in 21 career games, including 13 games for the Bears last season with two starts.
"Xavier Crawford we studied in the offseason as well, and we compared him to Justin Coleman," Schneider said. "He is a really talented nickel corner who Sean Desai coached in Chicago, so he was excited about coming out here and being a part of what we got going on."
The Seahawks currently have 15 players on their practice squad after signing 12 players on Wednesday, but can still add two more because linebacker Aaron Donkor does not count against the 16-player limit as part of the league's International Player Pathway Program.
