Watch: DeRozan leaps up to deny Lauvergne

With just 10 blocks on the season entering Tuesday's matchup, it was hard to imagine Toronto Raptors All-Star DeMar DeRozan coming through with a pivotal rejection, let alone stuffing someone at the rim.

Chicago Bulls big man Joffrey Lauvergne went up for a two-handed dunk with minutes to go in the fourth quarter, but DeRozan made sure he couldn't throw it down with a crucial defensive play.
