"49ers running back Frank Gore isn't happy with his contract. He's frustrated regarding the lack of progress on a new deal, and he won't comment on a PFT report that he could soon request a trade.

Coach Jim Harbaugh has dismissed accounts of frustration and a possible trade request as "water-cooler talk." Meanwhile, G.M. Trent Baalke has expressed a strong desire to keep Gore around.

"The best thing we can say is we're doing everything we can to make Frank a 49er for life and whether that gets accomplished in the near future or not remains to be seen," Baalke told Pat Kirwan and Tim Ryan of SiriusXM NFL Radio. "But Frank's a 49er. He's a heck of a football player, he's a heck of a young man, and he's a leader. You can't say enough good things about Frank.""
