EDEN PRAIRIE, Minn. — The Vikings on Thursday announced the signing of veteran free agent quarterback Mike Kafka.

The former fourth-round pick of Philadelphia in the 2010 NFL Draft participated in last month's first-ever NFL Veteran Combine, an event that brought together more than 100 free agents with various levels of prior experience in the league.

Kafka backed up Michael Vick and Kevin Kolb during his rookie season and Vick and Vince Young in 2011, appearing in four games and completing 11 of 16 passes (68.8 percent) for 107 yards that season.

Kafka suffered a hand fracture during the preseason in 2012. He was signed by New England to a reserve contract in January 2013, then claimed on waivers by Jacksonville in June of that year. Kafka was released before the regular season and was signed by Tampa Bay in 2014. Kafka spent parts of last season on the Buccaneers active and practice squad rosters.

The Chicago native played collegiately at Northwestern, becoming the Wildcats starter in 2009. Kafka set an all-time bowl record with 47 completions and 78 passing attempts in the 2010 Outback Bowl where he also set team and bowl records with 532 passing yards.

Kafka finished his college career 408-of-637 passing for 4,265 yards with 19 touchdowns and 268 carries for 887 yards and 11 rushing scores.

Minnesota also announced on Thursday that it has waived quarterback Pat Devlin, who joined the Vikings as a reserve last November.
