The legendary forward met the media for the first time as a member of his new team Wednesday, moments after the club confirmed his one-year, $1-million contract.
The 45-year-old said he's leaning toward retiring after one last go-round.
"Ninety-nine percent (chance) this will be my last season," Jagr told reporters, according to Sportsnet's Roger Millions.
When asked about approaching Gordie Howe's all-time games played record, Jagr downplayed it by reminding reporters that he left the NHL for the KHL earlier in his career.
"I never thought about the record or I never would have gone back to Russia," he said, according to Sportsnet's Eric Francis.
As for his readiness for this season, the ageless winger said he won't rush himself into game action, making it clear he wants to get a few practices in before taking a spot in the lineup, according to Sportsnet 960 The FAN's Pat Steinberg.
