Nike received a temporary restraining order Wednesday that prohibits Reebok from selling or producing Tim Tebow-related products.
Nike claimed that Reebok International Ltd. used Tebow's name on Jets-related apparel without permission after it was announced last week that Tebow had been traded from the Denver Broncos to the New York Jets.
The Tebow trade took place right before Nike replaces Reebok as the supplier of NFL team uniforms on Sunday.
Judge P. Kevin Castel of the Southern District of New York banned Reebok from selling any apparel with the name Tebow on it unless it was made by March 1 and was Broncos-related.
The lawsuit, which seeks unspecified damages, claims Reebok misappropriated publicity rights, interfered with business relationships and unjustly enriched itself because it failed to get Tebow's permission for the new products, according to ESPN.
According to the lawsuit, Reebok did not respond to demands to cease Tebow apparel sales after a Tebow representative sent a letter to the company Mar. 23.
New Nike-supplied uniforms for all 32 NFL teams will be unveiled next week in New York City, beginning a five-year deal between Nike and the league. Nike will be the exclusive provider of jerseys and sideline apparel for all NFL teams after a decade of Reebok being the sole provider.
According to ESPN, demands for Tebow-related Jets apparel was intense last week during a normally subdued time for NFL merchandise sales.
The lawsuit stated that Nike believes Reebok was shipping large amounts of Tebow-related apparel to retailers for public sale this week, damaging Nike's ability to capitalize on a short-lived opportunity because it is unlikely that a consumer will buy two Tebow jerseys in two weeks.
