Linebacker Cullen Gillaspia, who plays exclusively on special teams, suffered a knee injury during a Seahawks punt in the 3rd quarter of last Sunday’s 31-21 win. He did not return to the game and according to Pete Carroll, Gillaspia will need surgery.
Injury updates from Carroll: Backup LB/ST standout Cullen Gillaspia needs surgery after injuring his knee yesterday. It's not as bad as initially feared but will still be a long haul ... They're hoping to get WR Marquise Goodwin and Darrell Taylor back this week, but that's TBD.— Brady Henderson (@BradyHenderson) November 7, 2022
Carroll did not say it was a season-ending injury but “long haul” sounds like another way of saying he’ll need to be placed on injured reserve.
Seattle’s currently at the maximum of 53 players on the active roster, but if Gillaspia is out long-term then it stands to reason that a spot will be made vacant through his absence. My guess is that cornerback Tre Brown will fill that spot in the coming days. Brown has been designated to return to practice but hasn’t officially moved to the active roster yet. There’s a 21-day window for him to be put on the active roster, and that window expires on November 16th.
