Darren Ferguson underlined his growing managerial reputation as his League One side Peterborough held top flight West Bromich Albion to a 1-1 draw in the FA Cup third round on Saturday.
Peterborough boss Ferguson is the son of Manchester United boss Sir Alex and he looks increasingly like a chip off the old block.
After leading Peterborough to promotion from League Two last season, Ferguson has masterminded Posh's surge into the League One play-off places.
Now they can look forward to hosting Premier League Albion in a replay at London Road thanks to Craig Mackail-Smith's equaliser with three minutes to play at the Hawthorns.
It was no more than Ferguson's side deserved for a battling display.
Mackail-Smith hit the woodwork in the first half and then missed a golden opportunity to equalise after Jonas Olsson had headed Albion in front after 64 minutes.
But in the 87th minute he grabbed his 18th goal of the season when converting a low cross from Aaron McLean.
Baggies boss Tony Mowbray had fielded his strongest available side and looked on their way to the fourth round when Olsson broke the deadlock with a header from skipper Jonathan Greening.
But Mackail-Smith had been a handful throughout and his dynamic performance kept Albion on the back foot.
George Boyd had the ball in the net after 76 minutes but the Posh forward had strayed offside. However, with three minutes left Mackail-Smith forced a replay when he turned home a cross from Aaron McLean.
