UFC Lightweight Champion Conor McGregor could be in hot water for his actions towards referee Marc Goddard at Bellator 187.The Notorious was in attendance at Bellator 187 last night to watch his teammate Charlie Ward fight against John Redmond. After Ward had won the fight, McGregor leaped out of his seat near cage side, and jumped inside the cage to celebrate with his teammate.This caught Goddard and the rest of the referees by surprised, who immediately ran over to the UFC champion to try and get him out of the cage. This was when the celebrations turned nasty, as McGregor went on to push the referee, but he was quickly restrained before he could do any serious damage.Goddard, who also clashed with McGregor recently during Artem Lobov’s fight with Andre Fili at UFC Fight Night 118 in Gdansk, Poland, spoke about the incident at Bellator 187 during a statement on his Twitter account.He tweeted: "I operate with integrity, belief and values. I hold MMA in a deep rooted place in my life and have considered myself most fortunate to have done so for so long."Family first. Everything else second. Respect."

Later on after his incident with Goddard, McGregor was then seen appearing to slap Bellator staff member Mike Johnson, who tried to stop him re-entering the cage.

Bellator have confirmed that they are looking into the incident, as they said the following in a statement, via MMA Junkie:

"We’re aware of the in-cage altercation involving Conor McGregor and a Bellator staff member. Viacom and Bellator hold the safety and well-being of our staff in the highest regard and we’re currently reviewing the situation."

Sure enough, McGregor is bound to receive some sort of discipline for his actions, but this shouldn't hold up an actual return to the Octagon for the first time in over a year. This fight is expected to be a unification fight with interim UFC Lightweight Champion Tony Ferguson, with many believing it could take place at UFC 220 in January 2018 at the TD Garden in Boston.

Notorious hasn't been seen competing inside the Octagon for UFC since he won the Lightweight title at UFC 205 by defeating Eddie Alvarez via TKO (punches) in the second round.
