Oregon State defensive tackle Stephen Paea will not participate in the remainder of Senior Bowl week because of a possible tear to the lateral meniscus in his knee, according to sources. Paea was undergoing an MRI on Tuesday after hurting the knee during Monday's opening practice. At 6-feet-1, 295 pounds, he was the Pac-10 defensive player of the year. In his most recent mock draft, RealGM's Jeff Risdon listed Paea as a first-round pick.
