STANFORD, Calif. -- Offensive tackle Kwame Harris will skip his senior season at Stanford to enter the NFL draft.

Harris started every game for the past two seasons with the Cardinal, who went 2-9 last season. The 6-foot-7, 308-pound Harris was chosen as the top lineman in the Pacific-10 Conference this season.

"I have spent many sleepless nights wondering if my decision to leave Stanford is the right one,'' Harris said Tuesday. "Although there is no clear-cut method of coming to an answer, my heart yearns for the challenges of the NFL.''

Harris is the second player to leave Stanford early, following receiver Teyo Johnson. Bob Whitfield, who left in 1991, was the only previous Stanford player to leave school early.
