Washington State's NCAA tournament hopes took a hit with the suspension of Pac-10 leading scorer Klay Thompson after his arrest for marijuana possession Thursday.

Thompson, who is averaging 21.4 points per game, will not play in the team's regular-season finale Saturday against UCLA.

"We are aware of the situation involving Klay and will continue to gather information," Washington State coach Ken Bone said in a statement released by the school. "The situation will continue to be evaluated throughout the weekend. Until that time neither myself nor the team will have further comment."

The incident occurred during a traffic stops shortly after Thompson scored 22 points in a 85-77 defeat of Southern California that improved the Cougars to 19-10.

Thompson is the son of Mychal Thompson, who was the first pick in the 1978 NBA draft and played for multiple teams in the pros, including the Los Angeles Lakers.

"The fact I'm extremely disappointed in him, obviously," Mychal Thompson told the Seattle Times. "I told him, 'Klay, we've all been there, we've all been to college, and had friends and teammates who smoked dope.' "I've been in that situation many, many times and chose not to do it. You've got to be better than that, you've got to be smarter. I told him I was extremely disappointed in him. He let the team down, he let the school down and he let himself and his family down. "I'm at a loss for words."
