Team owners and the referees' union reached an agreement on differences late Wednesday, and the referees will return for the Baltimore Ravens-Cleveland Browns game Thursday night.

Romney weighed in on the issue himself on Tuesday after a blown call by replacement referees gave the Seattle Seahawks a win over the Green Bay Packers.

"I'd sure like to see some experienced referees, some with NFL experience, come back out to the NFL playing fields," Romney said Tuesday evening in an interview with CNN.

On Tuesday, Obama also weighed in on the NFL referee lockout.

"And I say this as a Bears fan, who obviously is never heartbroken when the Packers lose, but it’s not just this game," Obama told the Des Moines Register. "We’ve seen that over the last several months. We need to go ahead and get this resolved and I think that is a bipartisan position."
