Jack Campbell said he has full movement in his lower body.

Campbell, who was carted off with a frightening neck injury in Week 8 against the Vikings, said in a statement that he is recovering. “I’m incredibly encouraged by the progress I’ve made in such a short period of time,” Campbell’s statement reads, in part. “I have full movement in my lower body, and I’m continuing to make progress with movement in my upper body. I know there’s still work ahead, but I remain very optimistic. I’m taking things one day at a time, staying positive, and focusing on getting better.” Campbell is likely out for the rest of the season, a blow to a Detroit defense that has struggled against both the pass and the run this season.
