WASHINGTON — Senators have asked the NFL commissioner to make game broadcasts on the NFL Network available on free television to more fans.

The league has said it provides free broadcasts in the home cities of competing teams. But 13 lawmakers said in a letter this week to Roger Goodell that the NFL is too narrowly interpreting what a home city is.

The senators want quick action so fans in every market receive free TV access to games played by their closest team or the team it has been historically aligned to. Eight games will air this season on the NFL Network, which is available in less than 40 percent of households.

ALAMEDA, Calif. — Former Oakland Raiders coach Lane Kiffin filed a grievance with the NFL Wednesday to claim the $2.6 million in lost salary he maintains he is still owed by the team.Kiffin was fired late last month for cause because of what owner Al Davis described as acts of insubordination and lying by his second-year coach.
