Quarterback Matt Cassel, set to become an unrestricted free agent this weekend, is re-signing with the Vikings, according to two NFL sources.

Cassel's new contract is for two years. He would be considered a bridge to the next Vikings quarterback, likely a draft choice this season.

Jason LaCanfora of cbsports.com reported the deal was worth $10 million. For comparison sake, the Jaguars signed another "bridge" quarterback, Chad Henne, to a two-year deal on Friday that is worth $8 million, including $4.5 million guaranteed.

The agreement was first reported by Ian Rapoport of the NFL Network (@rapsheet).

Cassel, 31, opted out of a two-year contract he signed with the Vikings in 2013 that was worth $7.4 million.

Vikings General Manager Rick Spielman has said, during the offseason, that the team would like to sign a veteran quarterback in free agency and also draft a college quarterback.

Teams are allowed to begin negotiating with unrestricted free agents who weren't with their teams last year on Saturday, but cannot sign them until Tuesday.

Cassel last spoke with reporters after the Vikings' season-ending 14-13 victory over the Lions in the last game at the Metrodome on Dec. 29, saying: "I love playing for the Vikings. The fan base here is absolutely amazing. The team was special. It was a great team to play for. I really enjoyed my time with my wife, myself, my kids, a great community and everything else that goes along with it. So, would I love to be a Minnesota Viking? Absolutely, without a doubt."

The Vikings have the eighth pick in the NFL draft on May 8. Of the first 11 teams drafting, five others have a need at quarterback. Four college quarterbacks — Teddy Bridgewater of Louisville, Blake Bortles of Central Florida, Johnny Manziel of Texas A&M and Derek Carr of Fresno State — are projected to be top-10 picks.

Cassel played in nine games for the Vikings last season, starting six. He was 25th in the NFL in passer rating (81.6). In a Dec. 15. victory over Philadelphia he had the best performance by a Vikings QB this season — 26-for-35 for 382 yards and two TDs.

Ponder is also under contract through 2014. The 12th overall pick in the 2011 draft, he signed a four-year contract for $10.15 million that is fully guaranteed. His signing bonus of $5.8 million is paid out evenly over the four years.

Cassel was a backup to Heisman winners Matt Leinart and Carson Palmer at USC, and is the only modern-era quarterback who never started a college game to have started an NFL game.

The Patriots drafted Cassel in the seventh round (230th overall) of the 2005 draft, and he was a backup to Tom Brady for four seasons in New England. In 2008, Brady suffered a season-ending knee injury in the first game, and Cassel played the rest of the season, leading the Patriots to an 11-5 record. With his four-year contract expiring, the Patriots gave him the franchise tag early in 2009 and traded him to Kansas City for linebacker Mike Vrabel and a second-round draft choice.

Cassel's big season with the Patriots paid off. The Chiefs signed him to a six-year, $63 million contract that included $28 million in guaranteed money. He started in 2009, and in 2010 made the Pro Bowl as Kansas City won the AFC West. He injured his hand after 10 games in 2011, however, and after starting in 2012 he eventually lost his job to Brady Quinn.
