The San Francisco 49ers have hammered out a six-year, $110 million contract extension with star quarterback Colin Kaepernick.

The deal includes a record $61 million guaranteed and averages $21 million annually.

“Colin’s hard work and dedication have played an integral role in the recent success of the 49ers organization,” general manager Trent Baalke said in a team-issued press release. “His work ethic, leadership and on-field production have positively influenced our team, and we look forward to his continued growth in all areas. Our organization always looks to reward our players for their contributions and commitment to the team.”

The negotiations were relaunched this week after being dormant since the NFL scouting combine in February.

"I really expect that real breakout year for Colin," 49ers coach Jim Harbaugh said recently. "He just has the look and feel that he's going to break out, more so than he already has. I'm really excited about everything about his game right now.

"Athletically, he looks bionic. We all remember the 'Six Million-Dollar Man.' That's what he looks like to me. He's very gifted and he always has been."

A 2011 second-round draft pick from Nevada, Kaepernick has ledt the 49ers to consecutive NFC championship games.

Kaepernick passed for 3,197 yards and 21 touchdowns last season, rushing for 524 yards and four touchdowns.

"I feel like we have a lot of firepower in our corner," Harbaugh said. "I feel like we have a lot of ammunition in our camp. I was just thinking about it the other day, 'It doesn't get better than this.'"
