The cornerback was injured on Saturday night when he was hit by a Texas A&M player. The play was originally ruled targeting by the officiating crew, but the replay umpire overruled the call.
"He tore three ligaments in his knee, also dislocated his knee and he also dislocated his shoulder so it's a pretty tough deal.," Malzahn said.
"He has done an outstanding job for us as a true freshman, on special teams and on defense, so that's a big blow for us," the coach added. "We'll definitely be thinking about him."
Dinson was credited with nine solo tackles and six assists while playing in nine games with one start this season.
“He’s a wonderful person, always has a smile on his face," Malzahn said. "He comes to work, works extremely hard. He really had a big role on special teams. As of late, the last two weeks' games, he was coming on playing a lot of snaps on defense. He is just a wonderful person--really disappointed for him. Hopefully, he’ll recover.”
