The Minnesota Vikings have signed quarterback Mike Kafka and defensive end Caesar Rayford.
Both players took part in the NFL veteran combine in Arizona.
Kafka spent the 2014 season with the Tampa Bay Buccaneers as the third-string quarterback behind Josh McCown and Mike Glennon. Kafka has not appeared in a regular season game since 2011 when he played sparingly in four games for the Philadelphia Eagles.
Rayford was traded from Indianapolis to Dallas in 2013 after a standout preseason with the Colts. Rayford appeared in seven games for the Cowboys and recorded five tackles. He spent the 2014 split between playing in the CFL and the Arena League.
