PORTLAND, Ore. -- Police in Oregon say Detroit Lions defensive tackle Ndamukong Suh crashed his car into a tree in downtown Portland, but was not injured.

Police say Suh was not impaired and was cooperative with officers following the accident at about 1:15 a.m. Saturday. Suh lost control of the 1970 Chevrolet Coupe he was driving, which then hit a curb, light pole, drinking fountain and tree. His vehicle was towed from the scene.

Suh had two passengers in the vehicle. They were not injured.

Suh is a graduate of Portland's Grant High School. He was the NFL's 2010 defensive rookie of the year. On Tuesday, the league suspended him for two games for stomping the arm of Packers guard Evan Dietrich-Smith.
