According to the MRI, McKillop tore the anterior cruciate ligament (ACL) and patellar tendon in his left knee during yesterday’s practice. The second-year linebacker out of Pittsburgh landed awkwardly after jumping for a ball. He was carted off the field.
McKillop was third on the depth chart at inside linebacker behind Patrick Willis and Takeo Spikes. McKillop looked to be the eventual starter next season if Spikes does not return to the team.
Veteran Matt Wilhelm and rookie NaVorro Bowman look to be the two candidates to take the vacated spot.
