USC has suspended star junior forward Chimezie Metu for the first half of Thursday’s game at California after he was ejected for striking Washington State’s Carter Skaggs in the groin in Sunday night’s 89-71 win. Metu was also stripped of his captaincy and required to write an apology letter to Skaggs. “I understand there is no place in the game of basketball for such an unsportsmanlike action,” Metu wrote in the letter. The Pac-12 approved USC’s disciplinary actions and will take no further action. Metu, who leads the Trojans scoring 17.8 points per game, was named a captain for the first time this year. Coach Andy Enfield said before the season Metu earned the honor by showing more leadership and maturity, but Enfield cautioned that Metu had to show it in games.
