Several Nike employees have reportedly been hit with subpoenas in connection with the college basketball bribery scandal

As the FBI announced the arrests of 10 people involved in a widespread college basketball bribery scandal on Tuesday, investigators warned that the probe could grow as it dug down into the "dark underbelly" of college basketball.

Now, several employees working with Nike's Elite Youth Basketball League have been hit with subpoenas, according to ESPN.

Nike was not specifically named in the three complaints that were filed by the Department of Justice on Tuesday.

Nike's youth league is one of the most important places for high school-aged basketball players to strut their stuff for college coaches and scouts, and it's a major focus of recruiting for Division I basketball programs.

Three of the four assistant coaches that were arrested on Tuesday are employees of schools with Nike sponsorships: Oklahoma State University, University of Southern California, and the University of Arizona.

Nike told Business Insider in a statement that it "believes in fair and ethical play, both in business and sports, and strongly opposes any form of manipulation," but declined to comment further.

Jim Gatto, the director of global sports marketing for basketball at Adidas, was also among the defendants. Gatto is accused of conspiring with coaches to pay high-school athletes to play at universities sponsored by Adidas (referred to as "Company 1" in the case).
