"I don't like it," Nylander said Friday, speaking publicly for the first time since missing a week's action with severe migraines.
"I mean, the games are crazy to watch from home. I've never been so nervous in my life."
Nylander was the only Leaf to play all 82 regular-season games, and his attendance had been perfect through his first seven NHL post-seasons.
As with anyone employed by the Maple Leafs, Nylander declined to detail his health issues — "Look, that's just personal, so I'm not going to get into that," he said, "but anything else you guys want to discuss" — and he refrained from confirming his participation in Game 4.
Yet all signs point toward Nylander making his series debut, and the Leafs receiving an offensive and emotional jolt, on Saturday.
