"Regardless of where this series ends up, or whether we are down, up, facing elimination, we're going to do what is right," San Jose coach Peter DeBoer said Friday. "He's going to do what's right. We're not looking to buy time. We're not looking to rush him back if we get in a spot where we're in trouble.
"It's too serious an injury and he's too valuable a guy. We're going to do what's right."

Game 2 of the best-of-7 series is Saturday (10:30 p.m. ET; NBCSN, SN360, TVAS, PRIME, NBCSCA).
Thornton, who has been out since Jan. 23 recovering from knee surgery, is skating and getting closer to playing. He was in warmups Thursday, which made it appear he might play in the series opener at Honda Center.
"Obviously he's making progress or he wouldn't be out there," DeBoer said. "It probably grabbed their attention for a little bit.
"There's no secret to it. There's nothing there. It's no gamesmanship. He wants to be around the group and he's getting closer and that's where he was."
Thornton said Thursday his knee felt great after he increased his workload the previous day. The Sharks did not practice Friday.
"If I come in, I want to stay in for the full run," the 38-year-old said Thursday. "So that's my focus, come back healthy enough that I can play every night and [have it] work out good for the guys. And not just be there, be a difference out on the ice some nights."
