The Toronto Maple Leafs signed and traded star right winger Mitch Marner to the Vegas Golden Knights Monday, ending the 100-point player's stint with the team and leaving a massive hole at a key position on the offensive side of the puck.

On Tuesday, things became official, and Marner became a member of the Vegas Golden Knights. The 28-year-old was traded for forward Nicolas Roy and signed an eight-year contract extension worth an AAV of $12 million.

The Vegas Golden Knights acquired Mitch Marner in a sign-and-trade with Toronto on Monday, according to a person familiar with the move. The person spoke to The Associated Press on condition of anonymity because the deal had not been announced.
