OMAHA, Neb. (AP) -- Michael Huyghue has announced his resignation as commissioner of the United Football League.

Huyghue has been the second-tier pro league's commissioner since its inception in 2009.

Huyghue said in a statement Tuesday that the UFL has "experienced significant funding issues" and that it seems "most prudent" that he step aside while owners attempt to raise funds for the 2012 season.

UFL majority owner and founder Bill Hambrecht said he and other owners are committed to playing a fourth season.

The 2011 season ended prematurely, with each team playing four of its six scheduled games. The UFL has lost more than $100 million the past two years.

The league, whose headquarters are in Jacksonville, Fla., had teams in 2011 in Las Vegas; Norfolk, Va.; Omaha, Neb.; and Sacramento, Calif.
