Arsenal legend Robert Pires has allegedly been punched by an opposing coach in the Indian Super League.
The Frenchman, currently playing for FC Goa, claims he was hit by Atletico de Kolkata coach Antonio Lopez Habas at half-time during a 2-1 loss.
"Both teams have written to the ISL and the incident has been referred to the regulatory commissioner," an ISL spokesperson told Reuters.
Cavin Lobo's scored twice for Kolkata to earn the points following Andre Santos' opener for FC Goa.
"The other thing that happened which is more serious is that one of our players said that he was beaten by the coach of the other team," FC Goa coach Zico said after the match.
"Pires said he was punched in the face by the Atletico coach and it is very shameful.
"I am telling you what my players told me and I didn't see that myself but I don't think that Pires will lie and say something that didn't happen."

Arsenal manager Arsene Wenger believes Tottenham will never maximise their potential on or off the field until they have moved to a new stadium.
This evening the two north London sides will go head to head at the Emirates Stadium, the Gunners' 60,000-seater home since 2006 for which the club continue to pay off at around £35 million per year against a long-term fixed interest rate bond.
Wenger said: "You cannot be in a business where you turn down 15,000 or 20,000 people every week. If your competitors have more financial power than you, at some stage you have to make a decision."
The Manchester United manager Louis Van Gaal has said the club agreed to sell the England striker Danny Welbeck to Arsenal because he did not have the goalscoring record of other strikers at the club.
Welbeck joined the Gunners right at the end of the transfer window after United brought in Colombian striker Radamel Falcao. He scored ten times for United last season.
"With Danny Welbeck, yes, he was here from when he was nine. After coming back from Sunderland he has played three seasons for Manchester United. But he doesn't have the record of Van Persie or Rooney, and that is the standard."
Welbeck could get his first game in an Arsenal shirt against Manchester City on Saturday.
Arsenal have announced the signing of England international forward Danny Welbeck from Barclays Premier League rivals Manchester United for an undisclosed fee.
The 23-year-old, who is currently with Roy Hodgson's national squad ahead of fixtures against Norway and Switzerland, has signed a long-term deal at the Emirates Stadium to become Arsene Wenger's fifth summer signing - with the deal announced almost two hours after the initial transfer deadline had passed.
He leaves United after coming through the ranks at Old Trafford - developing his craft with loan spells at Preston and Sunderland - but new Red Devils' boss Louis van Gaal has allowed the player to leave in search of regular first-team football.
Arsenal have agreed a deal in principle to sign Manchester United and England forward Danny Welbeck as talks continue to complete the deal before the close of the transfer window.
The 23-year-old appears set to be given the opportunity to leave Old Trafford.
The Gunners must secure a deal before the 11pm deadline.
