The New England Patriots released Tim Tebow on Saturday, a move that leaves the polarizing quarterback's future in doubt.

The Pats' decision to cut ties with Tebow before Saturday's 6 p.m. ET 53-man roster deadline was first reported by ESPN NFL Insider Adam Schefter.

Tebow, who signed with the Patriots in June, struggled to find consistency throughout the preseason, completing 11 of 30 passes for 145 yards with two touchdowns and two interceptions in three games. He also ran 16 times for 91 yards.

Tebow took to Twitter to thank the Patriots.

I would like to thank Mr. Kraft, Coach Belichick, Coach McDaniels and the entire Patriots organization for giving me the opportunity... — Tim Tebow (@TimTebow) August 31, 2013

Tebow cleared waivers Sunday, making him a free agent. He has no doubt that he still wants to be an NFL quarterback.

"I will remain in relentless pursuit of continuing my lifelong dream of being an NFL quarterback," Tebow wrote on Twitter.

After sitting out the club's third preseason game, Tebow had his final chance to impress coach Bill Belichick on Thursday night against the New York Giants. He completed 6 of 11 passes for 91 yards with two TDs and one interception while also getting sacked four times.

"It's not just one game [that matters]," Belichick said Friday about the player evaluation process, "although every game is important. But the body of work, the camp, the rate of improvement, the ability to do the things that players are going to be asked to do at their respective positions [also matters]."

Asked after Thursday's game if he was worried about sitting on the roster bubble, Tebow was his calm self.

"I'm blessed, because of my faith, that I don't have to worry about the future because I know who holds my future," Tebow told reporters. "It's something I try to live by. It really gives you a lot of peace in whatever circumstance I'm in."
