The San Francisco 49ers have quarterback Colin Kaepernick under contract, but negotiations with coach Jim Harbaugh on an extension have stalled.

According to ProFootballTalk.com, the 49ers made an offer to Harbaugh, but he has not responded to it.

Harbaugh reportedly wants to be paid the same as a coach who has won a Super Bowl. He has denied he is seeking to be the highest-paid coach in the NFL. He has guided the 49ers to a Super Bowl appearance and three straight NFC title games since taking over as coach in 2011.

Harbaugh is signed through the 2015 season. A previous effort last year to extend his contract failed, and there were reports the Cleveland Browns attempted to "trade" for Harbaugh earlier this offseason. He could opt out early but has publicly insisted he will remain with the 49ers for the final two years of his deal.

Harbaugh did not address his contract situation Friday, but did offer his compliments on Kaepernick receiving a deal that guarantees him $61 million and reportedly up to $126 million over six years.

"I think it was a great life-changing moment for Colin, for our team," said Harbaugh. "I'm equally as excited about it. Colin is a great football player and a great teammate, and also going through a season now not having to think about contracts or questions about longevity, and maybe pressure on him to put up certain statistics or numbers.

"Now he's in a position where he knows, and our team knows, and Colin can grow as a player, and I'm most excited about that."
