49ers tight end George Kittle underwent core muscle surgery after last season, leading to a nearly 30-pound weight loss. Despite playing through injuries like a fractured rib, shoulder issues, and a toe problem, Kittle missed only one game. He couldn't train for a month post-surgery but is now aiming to regain 10 pounds to reach his playing weight of 250 pounds. Kittle, entering his eighth season, remains optimistic about his recovery and feels close to 100 percent, following his second All-Pro season.
