The Seahawks reverted Mannion to the practice squad Monday.
EDGE Analysis
Mannion was elevated by the Seahawks on Dec. 9, just one day after joining their practice squad after being let go by the Vikings on Nov. 28. He was active for Sunday's 28-16 loss to the 49ers with Geno Smith (groin) ruled out for the game, and the former acted as the backup to Drew Lock. Mannion didn't see the field Sunday, though he could operate as the QB2 for Week 15 against the Eagles if Smith is unable to play.
