Davis has turned into a mauler in the 49ers' running game and has improved greatly in pass production -- and he was rewarded for his efforts Friday.
Davis signed a five-year, $37.295 million contract extension that will keep him under contract through 2019, a source told NFL.com's Albert Breer. The deal, which was first reported by ProFootballTalk, includes $17 million in total guarantees, according to Breer.
"Anthony is a very hardworking, dedicated and talented young player who has earned the respect of our entire organization," 49ers general manager Trent Baalke said in a statement. "Having already made significant strides early in his career, Anthony is just beginning to realize his full potential. We look forward to watching him achieve even greater results in the years to come."
