(MCT) — Attack Athletics, an elite West Side athletic training facility built by Tim Grover and backed by his most famous client, Michael Jordan, may be headed for foreclosure.

Grover's company, Attack Properties LLC, is in receivership and owes more than $12.2 million to creditors. Among those with substantial skin in the game is Jordan, who stands to lose $1.5 million as an unsecured creditor.

Attorneys representing Attack Properties and Jordan did not return phone calls inquiring about the case Thursday. A person answering the phone at the gym said Grover was in London and would not be taking any calls on the matter.
