A football team doctor saved the life of a second fan who fell ill while watching his team.
The game was stopped for nine minutes after a home supporter needed help.
The fan in the Jack Walker stand was in need of help and the team's doctors and therapists raced to the scene.
The game at Ewood Park was stopped after Chris Wilder of Middlesbrough told the referee about the emergency.
Fans took to social media to praise the actions of Wilder and the quick response of Dr Prichard and Chris Moseley and Adam Reed, who jumped over advertising billboards to get to the fan.
The whole team were asking after Tony Mowbray after he spoke after the game.
The club is very caring about the community and will be doing everything it can to support the gentleman and his family.
The fan was in a stable condition in the hospital, a spokesman for the team said.
The away side's team was first on the scene and was able to restart the gentleman's breathing.
The crowd doctor, medics and the staff of theBoro were with them.
After regaining consciousness, the supporter was taken by ambulance to the hospital, where he is alert and stable.
Our thoughts are with him and his family, and we hope that he makes a full and swift recovery.
The other employer of Dr Prichard said it was proud to see him demonstrate the best values of the health service.
The scenes on Monday night were similar to the ones at the Spurs game in October, when play was stopped for 20 minutes.
Dr Prichard was one of the medics who performed cardiopulmonary defibrillation on Alan George Smith before paramedics arrived to take him to hospital.
