EDMONTON — It seemed risky, but Edmonton Oilers head coach Kris Knoblauch was certain Aleksander Barkov’s goal was offside Friday.

Knoblauch won a tide-turning coach’s challenge in the second period of Edmonton’s 5-1 win over the visiting Panthers to help send the Stanley Cup final to a Game 7 in Florida.

Adam Henrique had just sent Rogers Place into paroxysms of joy by scoring Edmonton’s second goal when Barkov buried a loose puck seconds later.
