Cheltenham manager Mark Yates toasted goalkeeper Scott Brown and the Whaddon Road crowd after Town's 1-0 win over Gillingham.
Defender Michael Hector scored the only goal of the game, heading home a Billy Jones corner midway through the second half.
It denied already-promoted Gillingham a League Two title party upon boss Martin Allen's return to his former employers, and left the fourth-placed Robins just two points off the automatic promotion places themselves.
Robins boss Yates said: "Scott trained on Thursday and had a massive whack on the foot. To be fair to him and physio Ian Weston, they have got a proper egg-sized lump down and that shows the character he has and the character we have in the squad. He deserves a special mention because he has put a shift in for the boys.
"Connor Roberts was all set to play but Scott has played through the pain - he had a couple of painkillers and put in a lot of hard work between Thursday and now.
"The crowd were good and were our 12th man - and we need a good following down at Exeter (next Saturday). The players have shown when we have got the support and the backing that we are a good side. We have beaten some good sides here and it's often when there is a decent crowd and we rise to the challenge."
Aside from Hector's header, Cheltenham had other chances as they pinned the league leaders in their own half for much of the second half.
"We were outstanding and have taken four points off the probable winners of the league - and the best team in the league," Yates said. "We showed we had that aggression and that competitive edge. To a man they were one million per cent better than they were last week (in defeat at Plymouth).
"Everything was just spot on - and it has been all week. Hopefully we can now go and do something next week and take it to the last game of the season."
