Bradford City took a big step towards League Two safety after a comfortable win over nine-man Southend United.
After a cagey opening the Bantams went ahead when James Hanson headed home Michael Flynn's cross.
Nahki Wells was fouled in the area by last man Sean Clohessy, who was given his marching orders, before Craig Fagan lashed home from the spot.
To compound the Shrimpers' misery, substitute Elliot Benyon was sent off for an off-the-ball altercation.
The victory moves Bradford up to 18th in the League Two table and more importantly means they are now seven points clear of the relegation zone.
Southend remain in fifth, three points outside the automatic promotion places but they have played a game more than third-placed Crawley.
VIEWS FROM THE DRESSING ROOM
Bradford City boss Phil Parkinson told BBC Radio Leeds:
"It was a crucial win, it was a massive game for us. One win can change the picture dramatically.
"It was a very special performance, we set out what we wanted to do, which was put the ball in behind Southend's back four because we felt we could exploit them.
"We handled them really well. We were calm, we were assured and that's what we needed."
