However, coach Jim Harbaugh anticipates the nine-year veteran to have several more solid seasons toting the rock.
"I really think Frank has three more good years," Harbaugh said Wednesday at the NFL Annual Meeting, per CSN Bay Area. "I truly believe that. But we're in a game of taking it one year at a time."
Gore is set to earn $6.45 million on the final season of his four-year, $25.9 million contract he signed in 2011. The running back is coming off his third consecutive season without missing a game and logged his seventh 1,000-plus yard campaign in his nine years.
The bulldozing back is still the best runner on the 49ers roster, but his average per carry did dip as last season progressed. If Harbaugh wants his three-year prediction for Gore to come true, he'd be wise to give the veteran a bit more rest in 2014.
