Dorsett signed with the Seahawks' practice squad Thursday, Ian Rapoport of NFL Network reports.
Dorsett was on the Seahawks' roster for the entire 2020 season, but he didn't play a game due to a foot injury. The 2015 first-round pick suited up for the Jaguars in Week 3 against the Cardinals but logged just one target on seven offensive snaps. He was subsequently cut. The speedster could get an opportunity if Tyler Lockett (hip) or DK Metcalf (foot) miss time.
