Hubbard has been competing with veteran Reggie Bonnafon for the Panthers' backup tailback job during training camp, Joseph Person of The Athletic reports.
Hubbard was selected in the fourth round after a productive college career at Oklahoma State. He wasn't used often in the passing game, however, and has drawn mixed reviews in that department through training camp thus far. After Bonnafon played just two games due to injury last season, it'll be interesting to see whether he or the rookie Hubbard becomes superstar Christian McCaffrey's top understudy prior to Week 1.
