The NHL has suspended him for the final three games of the exhibition season, but the winger will be available when Toronto opens its 2013-14 season against Montreal next Tuesday.
The incident came during Sunday's ugly game between the division rivals. After Buffalo's Corey Tropp was injured in a fight with Toronto's Jamie Devane, Scott attempted to go after Kessel on the next shift.
Kessel slashed Scott twice and give him a spear and was ejected from the game. The incident sparked a bench-clearing brawl, which resulted in Leafs forward David Clarkson being suspended for 10 regular-season games for leaving the bench and Buffalo coach Ron Rolston being fined for "player selection and team conduct."
