Defensive end Nick Bosa withdrew from Ohio State in October to begin a 12-week rehabilitation from core muscle surgery and prepare for the NFL draft.

His school made it to the Rose Bowl without him. When he attended one of the Ohio State practices in Southern California, where he is training, he met 49ers general manager John Lynch.

The 49ers own the No. 2 overall pick, and Bosa is a distinct possibility as the club looks for an upgrade at edge rusher. Of course, the Arizona Cardinals will have the first shot at Bosa with the first pick in the draft.
