Johnson underwent shoulder surgery on March 4 and should be ready to play in early August, according to a recent letter from his surgeon (Dr. Peter Millett, highly respected sports surgeon). All reports, including from a follow-up exam by another doctor, indicate a smooth recovery process so far. Medical evidence suggests that the outcomes after this surgery in NFL athletes likely depend on the size and location of the tear, but the most common types of tearing seen in multiple studies of NFL combine participants are not associated with decreased games played or started. Therefore, our overall concern level is relatively low.
