San Francisco 49ers quarterback Colin Kaepernick is at the crossroads of his career following a 17-3 loss to the Green Bay Packers, which was after he had the worst game of his career against the Arizona Cardinals in Week 3, according to NFL.com.

The 49ers lost 47-7 against the Cardinals, with Kaepernick throwing four interceptions and two pick-six, which are the worst for his career and one the most terrible performances in recent memory. The report also noted that the quarterback could be benched in favor of backup Blaine Gabbert in week five versus the New York Giants.

But the 27-year-old is not worried about his role going forward, telling the Sacramento Bee, "I don't play for job security. Whether football's here or not, I will be fine. I go out, I play to win. I'm not worried about job security when I step in this building."

49ers head coach Jim Tomsula has his full support as he plans to start Kaepernick against the Giants. "I want a confident man, full-bore ahead at that position. I believe it's critical. And I believe in the quarterback. I believe in Colin Kaepernick," Tomsula told the news outlet.

Kaepernick has regressed, especially his efficiency since leading the 49ers into the Super Bowl last 2012, wherein they lost to eventual champions Baltimore Ravens, per Washington Post. The report added that since 2013, San Francisco's offensive line has declined after the departure of Michael Crabtree and Anquan Boldin.

ESPN reports that if his struggles continue, the 49ers will have a difficult time moving Kaepernick due to his large contract. He signed a six-year, $126 million contract with 49ers in 2014, which includes a $12 million signing bonus and $61 million guaranteed money, giving him an average annual salary of $19 million, per Spotrac.

ESPN further noted that the 49ers can part ways with their starting quarterback before April 1, 2016 because the guarantees in Kaepernick's contract do not vest until April 1, which could save the team about $9 million. The only setback from the deal is the $61 million guaranteed money for injury protection.

For now, the 49ers will stick with their starting quarterback before making a decision by April 1 of next year. The Sacramento Bee also stated that the 49ers constructed the contract, which was approved by Kaepernick, so that they can get out of the deal every year by the April 1 deadline without any difficulty.
