Northampton boss Colin Calderwood expects the Football Association to investigate a touchline row which led to Stevenage Borough goalkeeping coach Lionel Perez being sent off during yesterday's FA Cup tie at Broadhall Way.
The incident took place after Scott McGleish had scored a penalty to give League Two Northampton a 2-1 lead over the Conference side with 10 minutes of the second round tie left.
Frenchman Perez, a former Sunderland goalkeeper, was seen quarrelling with Northampton goalkeeping coach Dave Watson.
He then thrust his hand, with fingers extended, into Watson's face. Perez was sent to the stands by referee Darren Deadman.
A late Anthony Elding goal salvaged a 2-2 draw for Stevenage and the tie will be replayed at Sixfields.
Northampton manager Colin Calderwood told BBC's Match of the Day: ``I just managed to see what happened. There has obviously been an altercation and there is going to be an investigation by the FA at the very, very least.''
He added on the Northampton official website: 'Dave Watson got poked in the eye in the dugout and Lionel Perez was sent off. It was seen by both the police and the FA, so we will leave it to the authorities to deal with.'
George Boyd put Borough ahead in the fifth minute, but Northampton equalised through Pedj Bojic after 67 minutes.
McGleish slotted his penalty kick after Barry Laker bundled over Josh Low, but Elding replied to make it 2-2 to secure a replay.
