The Oklahoma State Athletic Commission has sent out a letter to MMA promoters claiming that they will not be accepting any applications to hold events after March 31, 2012. The OSAC claims that a threat from "out of state" could "greatly affect the Commission's ability to provide for ... the health and safety of the fighters."

According to a report on KOKH Fox 25 in Oklahoma, the UFC is threatening to sue the state unless the Commission stops taking a 4% tax on Pay-Per-View events to fund its activities. MMA Worldwide has more including the letter from the OSAC after the jump:

From MMA Worldwide:

Combat sports are a multi-million dollar industry in the state, and now it seems that mixed martial arts will be slipping back into the shadows indefinitely.

This move will effect nearly 200 events that happen each year across Oklahoma, and if the UFC and the state can't come to terms... promoters will have to take their business onto tribal grounds and casinos where they have their own regulations.
