Portland Trail Blazers center Festus Ezeli will likely undergo season-ending surgery on his left knee, league sources told The Vertical. Ezeli's representatives at BDA Sports and the Trail Blazers have not yet finalized the surgery, but he's strongly leaning toward the procedure, sources said. Ezeli had been contemplating surgery in recent weeks due to an ailing left knee that has failed to adequately respond in rehab, sources said.
