Referee Darren Drysdale locked heads with Ipswich midfielder Alan Judge in an extraordinary exchange during their goalless League One draw with Northampton.

The official moved his head towards the Irishman in the final moments of the match and then briefly appeared to square up to the 32-year-old, before being ushered away by Northampton's Lloyd Jones.
