49ers' Jarryd Hayne: Retires from NFL

Hayne announced his retirement from the NFL on Sunday, CSN Bay Area reports.

Analysis:

Hayne's brief NFL career has come to an end. He was asked to join the Fiji Rugby Sevens for the upcoming Olympic games, and it was an opportunity he could not pass up. While he never was a big contributor, Hayne can say that he suited up for an NFL team despite having little to no experience playing the sport. That is no easy task.
