Dieffenbach was replaced by Madden Iamaleava, whose older brother Nico was the Bruins' starting signal caller before he suffered a season-ending torn ACL versus Oregon on Oct. 11.
Dieffenbach suffered an upper-body injury, per the FOX broadcast crew. He didn't come out of the locker room to start the second half.
More to come.
