Seattle Seahawks safety Jamal Adams left Monday's game against the Denver Broncos with a left quad injury.
Adams appeared to sustain the injury while attempting to sack Broncos quarterback Russell Wilson in the first half. He planted his left foot on the tackle attempt and landed awkwardly to the turf. He was able to limp off the field, but eventually left for the locker room on a cart.
According to an ESPN report, Adams "screamed out in frustration" while receiving treatment on the sideline. The Seahawks initially ruled him as doubtful with a knee injury.
Seahawks coach Pete Carroll said after that Adams had sustained "a serious injury" to his quad, but didn't provide any other details.
"He hurt his knee tonight. Not a typical knee injury," Carroll said, via PFF's Doug Kyed. "His quadricep tendon I think got damaged. He got hurt. It's a serious injury."
Adams, 26, is a three-time All-Pro and the anchor of Seattle's secondary. Following a 2020 trade from the New York Jets, Adams signed a four-year, $70.6 million extension with Seattle in 2021 that at the time made him the highest-paid safety in the NFL. Any extended injury to Adams is a significant blow to Seattle's defense.
The Seahawks edged out the Broncos 17-16 to take the win and close out Week 1 of the season.
