Thompson told coach Steve Kerr after the game he would be fine, but a scan on Monday confirmed a "mild strain of the hamstring".

The Warriors went on to win Game 2 109-104 in Toronto. The victory evened the NBA Finals at 1-1, with the series set to shift to Golden State for Games 3 and 4 on Wednesday and Friday respectively.

Thompson recorded 25 points, five rebounds and five assists before the injury. He knocked down four of six three-point attempts.

The Warriors are trying to win their third consecutive championship and fourth in five years.
