Thanks.From an NHL.com story, FWIW:
U.S. forward Brady Tkachuk said his brother, who was the focal point throughout the game Saturday, won't miss the final. Matthew's fight with Canada forward Brandon Hagel after the opening face-off set the tone for everything that followed. He had two goals and an ashist in a 6-1 win against Finland on Thursday.
"He'll be good to go for Thursday," Brady Tkachuk said. "Smart for him to rest up knowing that we'll already be there Thursday, and he'll be ready to go."

Hope Brady's right but in his role as team spokesman, I'll still take that "update" with a grain of salt.
