And also, the center Scott Lawtonwho has yet to play this season is unlikely to return, while fellow bottom-six forward Steven Lorenz is day-to-day.
Tanev, 35, is on injured reserve and has not played since Oct. 21, when he suffered an upper-body injury from an accidental hit to the head.
However, he said he is now in concussion protocol.
Tanev is in his second season in Toronto after signing a six-year, $27 million deal ahead of the 2024-25 campaign.
At Friday's training, Tanev paired up with attacking Oliver Ekman-Larsson.
Nylander, 29, has missed two of the last three games with a lower-body injury, the first regular-season contest he has missed since April 4, 2022.
He said he felt good, but “we'll see” about the game against the Flyers.
Nylander leads the team with 15 points (three goals, 12 assists) in nine games.
Jarnkrok, 34, has missed the last two games with a lower-body injury suffered while blocking a shot. He has three goals in eight games, but it is unclear whether he will make the squad despite being cleared to play.
Laughton, 31, was sidelined after blocking a shot in the preseason.
The Leafs acquired the veteran forward from the Philadelphia Flyers at last season's trade deadline. The Oakville, Ont., native had two goals and two assists in 20 regular-season games for Toronto and then added two more helpers in 13 playoff games.
Lorenz was injured in Wednesday's game against the Blue Jackets after crashing into the boards in the second period. He missed three games earlier this month with a previous upper-body injury.
