Terry is part of a group in talks with Colchester owner Robbie Cowling about a £14m takeover.
Terry's nephew Frankie Terry, also a defender, played 90 minutes for the U's in what was a third straight win for the club as they moved up to 12th.
Speaking after the game, manager Danny Cowley told BBC Essex: "It felt like a big night for the players, first and foremost, but also the club – I thought our supporters were incredible.
"I am really proud that in front of the eyes of many we are able to show a top version of what is a wonderful football club.
"We know this is a brilliant football club because we live it every day – there are some brilliant people at this club.
"We genuinely believe it has such high potential and we do need just a springboard to push on from and that is what we hope is on its way.
"I am so excited for our supporters. It is not easy supporting lower league clubs and Colchester United have not had it easy.
"Since Nicky (Cowley, brother) and I have been here we have been able to stabilise and find a good level of consistency but we all want more and I believe there are really exciting times ahead."
When asked if he had met John Terry, Cowley added: "I will talk about Frankie, because he was great tonight and he would have done his family proud, that is for sure."
