Jeremy Bloom, the world's No. 1-ranked moguls skier who wants to play football at the University of Colorado, filed a motion against the NCAA on Thursday, asking a Colorado district court to overturn a previous ruling that he could not accept skiing endorsements and play football for the Buffaloes at the same time.

"Although Jeremy relies on (his skiing) talents to sustain himself now, and plans to rely on these talents long after his football career ends, the NCAA says 'No' despite its own constitutional directives to foster the educational development of student-athletes and promote their welfare," says the motion, which asks for a temporary restraining order.

A hearing is set for July 31.

NCAA spokeswoman Jane Jankowski said the motion is premature because a waiver request from the University of Colorado is still pending.

"There should be a decision on this most likely by next week," Jankowski said. "There are some things in this motion that we haven't seen and we've encouraged the University of Colorado to submit any information to the NCAA that could have bearing on this."

Bloom would not comment on the motion.

The NCAA prohibits student-athletes from endorsing products based on their athletic ability. But Bloom petitioned the NCAA in January, contending that his skiing endorsements were unrelated to his ability in football. In February, on the same day Bloom finished ninth in the Olympic moguls competition, the NCAA denied his petition.

The 20-year-old Bloom, a highly touted wide receiver who helped Loveland (Colo.) High win a state championship, signed a letter of intent to play at the University of Colorado last year, but he has not enrolled at the school. The motion seeks a decision by a judge before Aug. 8 -- the day that Bloom is scheduled to report to the school in Boulder, Colo.

NCAA bylaws say that student-athletes are allowed to receive money for professional sports, including minor league baseball, as long as the only money being made is in salary. However, in professional skiing, there are no steady salaries, as income is comprised of prize money and endorsements.

Bloom promotes Oakley sunglasses, DynaStar skis and Under Armour performance apparel, but -- if he were to play football -- the NCAA won't allow him to endorse these products.

Bloom also has a modeling contract with Tommy Hilfiger Jeans.

In March, the NCAA's Jankowski told ESPN.com that Bloom could receive money from modeling as long as he satisfied four criteria. Bloom's modeling would have to have started before he enrolled; his modeling couldn't be based on his athletic ability (football); the company could not mention his involvement with NCAA athletics; and his pay would have to be commensurate with similar modeling contracts.

The NCAA has since said, according to the motion, that Bloom also wouldn't be allowed to make an appearance for the apparel company. Bloom could also drop all contracts and become eligible immediately.

The motion also seeks to stop the NCAA from prohibiting Bloom from earning money from appearances on TV shows and in films -- even if his appearances have nothing to do with football. Bloom has appeared on EXTRA, Access Hollywood and MTV and, according to the motion, Bloom has auditioned for several television programs and one New York casting executive said he has "star quality."

Bloom's lawyer Peter Rush successfully represented Northwestern running back Darnell Autry in his case against the NCAA in 1996. Despite the rule that previously prevented student-athletes from appearing in commercial films, Autry was granted a waiver and allowed to act in "The Eighteenth Angel," since the role had nothing to do with his football career. Autry, however, never got paid for the part.
