Strong suffered a wrist fracture similar to Cushing. In Cushing's case, the bone was fractured through and through. He continued to play with it for a long time without immobilization. Therefore the two separated pieces would not heal (non union) and at that late point in time, conservative immobilization in a cast would not have lead to healing.........therefore surgery was performed.
Strong also sustained a fracture of the navicular (also called the scaphoid) wrist bone. But this was a "stress" fracture, where the two pieces of bone did not actually separate and move. Strong was fortunate in that he played with this fracture since November 1 of last year and did not extend the injury to physical separation of the two pieces. Therefore, the wrist could be immobilized after the season for anywhere from 3-5 months depending on x-ray or other imaging findings. As long as he was not having pain, and was fully immobilized, he could have played with a cast on during this period of time.....but, of course, this would not very practical for a WR.
All in all, from the information that I have been able to garner, his wrist should not be an issue from this injury.
