Forty-year-old David James turned the clock back with a string of outstanding saves and drew the praise of manager Keith Millen as Bristol City made it six wins from their last seven npower Championship games.
The former England goalkeeper produced four one-on-one stops to deny Doncaster a result to ease their growing relegation fears and earned glowing praise from manager Millen.
The Robins boss said: "David continues to work so hard on his game and is looking fitter and sharper now than when he first joined us, which is a tribute to his enthusiasm.
"He made some important saves and we needed them because our first-half performance was so far below the standards we have set in recent weeks.
"The international break came at a bad time for us because we were playing well and you could see its' effect as we started the game very slowly.
"I really got stuck into the lads at half-time and the second-half performance was much better. I had every confidence that a goal would come because we have a lot of dangerous attacking players."
