After losing their last three games, the Boston Celtics can’t afford to drop Friday’s contest against the Toronto Raptors. Just ask Isaiah Thomas.

The Celtics point guard called Friday’s matchup in Toronto vs. the Eastern Conference’s No. 2 seed a “must-win.” Thomas might be right, as Boston currently is in a four-way tie for the East’s No. 4 seed and needs to turn things around if it wants home-court advantage in the playoffs.

The C’s will face a tough test in Toronto, which has earned wins in five of its last six games.
