The Buffalo Bills officially added quarterback Matt Cassel in a trade with the Minnesota Vikings on Tuesday.

The Vikings received undisclosed draft choices in the swap, and Buffalo received an undisclosed draft pick, the Bills announced in a press release.

According to multiple media reports, the Bills sent the Vikings their fifth-round pick in this year’s draft in exchange for Minnesota’s sixth-round pick. The Vikings will also receive a seventh-round pick in 2016.

Cassel played in 12 games over the past two seasons in Minnesota, completing 194 of 325 pass attempts for 2,232 yards, 14 touchdowns and 13 interceptions. The 10-year veteran is expected to compete for the starting job with EJ Manuel, who will be entering his third season.

Cassel, who will turn 33 in May, posted a 4-5 record with the Vikings. He opened last season as the starter before sustaining a season-ending broken foot in Week 3. He is the veteran quarterback the Vikings sought to compete with Manuel, with third-year quarterback Jeff Tuel re-signed to a reserve/future contract.

This winter, Buffalo also met with veteran quarterback Josh McCown, who ultimately signed with the Cleveland Browns.

Cassel, heading into the final year of his contract, is due to count $4.75 million against the 2015 salary cap ($4.15 million in base salary and a $500,000 roster bonus), compared to Manuel at $2.4 million and Tuel at $510,000. Kyle Orton, who retired after last offseason, will count $1.5 million in “dead cap” money. He was scheduled to count $5.5 million against the cap before retiring.

Cassel’s $500,000 roster bonus is due March 16, which prompted the Vikings’ to move him.

Cassel was the Patriots’ seventh-round pick in 2005 out of the University of Southern California. He was Tom Brady’s backup in New England for four years before spending 2009-12 as the Kansas City Chiefs’ starter.
