Tempers flare in 1st half of Spurs-Pistons game in a matchup of 2 of NBA's top teams

Pistons star Cade Cunningham was called for an offensive foul after extending his arms and knocking Spurs guard Stephon Castle down on the court. Spurs forward Keldon Johnson responded by pushing Cunningham and Pistons center Jalen Duren, who was recently suspended by the league, pointed his right finger in Johnson's face.
