Asked Thursday if any doubt has surfaced regarding his return in 2018, Sherman answered succinctly.
"Not in my mind," he said, according to the Seattle Times' Bob Condotta.
Sherman was also clear that he doesn't believe the injury will alter the way Seattle's front office approaches potential contract negotiations during the offseason.
"Honestly, I'm not sure [if it changes anything] on their side of things," he said. "It doesn't change anything in my mind. If we have the talks, we do. If we don't, it is what it is."
Sherman, who will turn 30 in March, is owed $13.2 million in the final year of his deal.
The Seahawks will save $11 million and incur a dead cap hit of just $2.2 million if they cut or trade him at any point before the start of the 2018 regular season.
Before hitting the shelf, Sherman tallied two interceptions, seven pass breakups and 35 total tackles in 2017.
