The Seattle Seahawks are already heading into 2022 with a massive rebuild, and one of their lone cornerstones may be out for at least a little while.

Jamal Adams, who the Seahawks acquired in 2020 via the New York Jets, missed Thursday's practice due to a hand injury that head coach Pete Carroll said the safety is "really concerned" about.

Adams had two fingers fused in the offseason after dislocating them several times over the last few seasons; however, something "just wasn't right" with that left hand.

"He's getting some opinions about it…" Carroll told reporters after Thursday's practice, via The News Tribune. "He's got to get it checked out. He's really concerned. He's really upset that he has to miss anything."

Carroll added that he did not know how long Adams would be out or whether surgery was on the table.

JETS' LE'VEON BELL SPARS WITH JAMAL ADAMS AFTER SAFETY IS TRADED TO SEAHAWKS

The Seahawks, who also got a fourth-rounder in the trade, sent the Jets two first-round picks, a third-rounder, and safety Bradley McDougald. They signed Adams to a four-year deal worth north of $70 million, with over half of that ($38 million) guaranteed. 

However, after missing just two games in his entire tenure with the Jets, Adams has missed nine games in his two seasons with Seattle and had a 60.1 PFF grade last year. He underwent surgery to repair a torn labrum that ended his 2021 campaign.

Meanwhile, the Jets have used their picks to select OL Alijah Vera-Tucker last year (using the third-round pick to trade up) and WR Garrett Wilson in this year's draft.

Adams is currently the highest paid player on the Seahawks after the team traded Russell Wilson to the Denver Broncos.
