Here is the full statement from 49ers RB Glen Coffee on his retirement from the NFL at the age of 23:
This has been a tough decision for me, but at this time in my life I feel it's best for me that I move on from football. I appreciate what the 49ers, my teammates and coaches have done for me, and I wish them a blessed season and all the best in the future.
49ers beat writer Matt Barrowss says Coffee was "as dedicated as anyone in the offseason, adding more than 10 pounds of muscle."
