The NFL filed a motion asking a Nevada court to dismiss Jon Gruden's lawsuit against the league, saying accusations that the NFL leaked Gruden's emails are "baseless" and "should be dismissed for failure to state a single viable cause of action."

The league responded Wednesday to the suit that Gruden filed in district court in Nevada's Clark County in November. 

Gruden resigned as coach of the Las Vegas Raiders in October with more than six seasons remaining on his 10-year, $100 million contract.
