NFL Media Insider Ian Rapoport reports the running back is in Texas to train on his own as the team begins workouts. CSN Bay Area first reported the news.
While the workouts are voluntary, James' absence is notable because he has been subject of trade rumors entering his third NFL season.
James would welcome a fresh start where he could get more playing time, the report from CSN Bay Area stated.
Not attending workouts is just one more indicator that the 24-year-old believes his NFL future lies outside of San Francisco.
