Ipswich manager Paul Lambert wants the EFL to investigate referee Darren Drysdale's confrontation with his player Alan Judge during Tuesday’s League One match against Northampton.
Lambert told talkSPORT on Wednesday: "I’ve texted Mike Jones (EFL head of referees) this morning to say have a look at the footage of the head thing.
"To me, in my opinion, it looks as if the referee went in there and I said to him after the game, 'Did you put your head in my player?’
"He couldn’t answer it and that’s the reason I spoke to Mike. I haven’t seen that in a long, long while."
The incident happened in the closing stages of the goalless draw at Portman Road.
Ipswich pair Flynn Downes and Jack Lankester and Northampton defender Lloyd Jones stepped in and calmed the situation before Drysdale booked Judge.
The Football Association confirmed on Wednesday morning that it is aware of the incident and it is understood Professional Game Match Officials Limited (PGMOL) will hold discussions with Drysdale and Ipswich.

Drysdale, who was appointed to the National List of referees covering EFL games in 2004, has also been a FIFA and UEFA assistant referee and was an assistant referee at the 2000 FA Cup final.
Judge's fellow Irish international Troy Parrott played the full 90 minutes for Ipswich last night.
The 19-year-old Tottenham striker has joined the Tractor Boys until the end of the season after his loan to Championship side Milwall was cut short.
