SANTA CLARA — Frank Gore isn't happy about the lack of progress in his talks with the San Francisco 49ers over a contract extension.
The two-time Pro Bowl running back said Monday that negotiations are "going slow" and he expects 49ers management to step up and work out a new deal before the regular season begins against Seattle on Sept. 11. He declined to comment about whether he would request a trade if there wasn't an extension in place by the opener.
"I would be upset," Gore said. "But I'm a football player. Like I said, I want to be here for my whole career, but it's up to (them) upstairs, the team. If they want me here, I want to be here."
The two sides don't seem anywhere close to reaching a new deal.
The Niners promised good-faith negotiations with Gore when he ended his four-day holdout and showed up for training camp. New coach Jim Harbaugh said Sunday he didn't sense any unhappiness in Gore and wouldn't get into what he called "water-cooler talk."
Gore is seeking a contract comparable to the $43 million, five-year deal running back DeAngelo Williams — 20 days older than San Francisco's star — recently received from the Carolina Panthers. That deal includes $21 million guaranteed.
Gore, making almost $5 million in the final year of his deal, said he plans to play out his contract but will surely test free agency next year if the 49ers don't give him an extension by his unofficial deadline.
"I'd like to get it done before the season, but right now things (are) not looking too good," Gore said. "But I'm going to come to work and be here for my teammates and try to do the best for me when I touch the green and play on Sundays."
The 49ers have shelled out big money previously.
On the eve of last season, they rewarded tight end Vernon Davis with a five-year extension worth $37 million overall, including $34 million guaranteed — making him the highest-paid tight end in NFL history. In May 2010, All-Pro linebacker Patrick Willis received a $50 million, five-year contract extension that takes him through the 2016 season and includes $29 million in guaranteed money.
