Bradford City boss Phil Parkinson apologised to his players for losing his rag during their FA Cup win over Millwall.
Parkinson and assistant Steve Parkin were both sent to the stands for their part in a mass melee in a frenetic first period that saw Millwall defender Mark Beevers dismissed and the home side score three times as Bradford produced another cup upset at Valley Parade.
After the 4-0 rout, Parkinson revealed: "There was a big prize at stake, to get the club into the fourth round for the first time in 15 years, so the tie at Stamford Bridge, we wanted to achieve that and we focused on the factors that would help us.
"I thought the lad that pushed James into the hoardings - I thought it was a dangerous challenge because there's a wall just behind them.
"Me and Steve reacted and ran down, as well as some of their staff, and the ref's decided to send me and Steve to the stands.
"I said to the lads at half-time I had to apologise for that because I had to ask them to keep their cool and stay on the pitch.
"But I'm glad it didn't ruin a great night. The lads didn't need us on the touchline anyway. It was nice and quiet for us in the stands."
