There was little question the hard-hitting safety would return if healthy, despite a vague social media post several weeks ago. Chancellor would forfeit $12 million in guarantees if he retired.
Turning 30 in April, Chancellor's $6.8 million salary for 2018 became guaranteed on Feb. 9.
The issue is whether the safety will be medically cleared to return to the field. The four-time Pro Bowler missed seven games in 2017 because of a neck injury. Coach Pete Carroll said in January that Chancellor could have a hard time playing football again.
Chancellor intends to give it a shot.
