Season ending and surgery.Just as serious as ACL tear and in some ways worse. 🙏 https://t.co/9NWIUYGjV0— David J. Chao - ProFootballDoc (@ProFootballDoc) September 13, 2022 Gilmore returned for the Panthers on Halloween 2021, but was on a tight snap count until Week 14, only a week away from the one-year anniversary. Adams, who is one of the best pass-rushing DBs in the league, has missed nine games in the last two seasons and was set to play this season with a cast to protect two fingers on his left hand. The 26-year-old had his chronically-dislocated ring and middle fingers surgically fused over the offseason, but suffered a fractured finger during training camp that the Docs said will need surgery. Before the injury, Adams had three tackles, one pass defended, and one QB hit through a little over a quarter of play. Seattle improved to 1-0 with the 17-16 win over the Denver Broncos. The Seahawks head to San Francisco next week to face the 49ers.
