IRVING — Though quarterback Tony Romo is progressing well in his rehab from back surgery, the Dallas Cowboys are looking for another quarterback or two to throw passes in the off-season program and minicamps.Veteran backup Kyle Orton is the only other quarterback on the roster.The Cowboys worked out former Philadelphia Eagles quarterback Mike Kafka, multiple sources confirmed.Kafka, a former fourth-round pick of the Eagles in 2010, was given “a look-see” by the Cowboys along with former Arena League receivers Braylon Bell and Maurice Williams.Kafka hasn’t played in the NFL since he was released by the Eagles before the 2012 season. He spent time in camp with the Jacksonville Jaguars in 2013 but was released before the season. Kafka didn’t play as a rookie and played in four games with the Eagles in 2011.Bell played at Abilene Christian in college but is a Dallas native out of South Oak Cliff High School.Williams played as a freshman at Pittsburgh before being ruled academically ineligible.

Hill Jr.Vikings seat licensesFifty yard-line season tickets in the lower section of the new Minnesota Vikings stadium come with an upfront license fee of $4,500 to $9,500 while a seat in the nosebleeds will set loyal fans back a $500 fee.The release of the pricing structure for the personal seat licenses, which the team is calling stadium builder’s licenses, coincides with a ramp-up in marketing for seats in the under-construction stadium set to open in 2016. Current season ticket holders have first rights to buy into the new building, with sales to them happening in waves over the next nine months. Those one-time charges are on top of the annual price of buying a ticket, which will go for $50 to $400 apiece per game.Three-quarters of the stadium’s 65,000 seats will have a license fee attached. Vikings ownership is using seat license proceeds to cover one-fifth of the $500 million private share for the $1 billion stadium.Briefly• Chiefs: Veteran defensive back Dunta Robinson, who never lived up to expectations last season, was released and Canadian Football League wide receiver Weston Dressler was signed.• Lions: Center Dominic Raiola re-signed to a one-year deal, his 14th season with Detroit.• Vikings: Linebacker Erin Henderson, who was recently arrested twice on suspicion of drunken driving, was released.
