On Monday afternoon there was a change of heart with Gabbidon, along with Rhys Weston, Leo FW and Jason Bowen added to the 16 on duty on Saturday.
Lennie told Mondays press conference
"I'm not ruling Danny out. You'll have to wait and see what happens but we've had a long and intense training session today and Danny was very good in it.
"If I had the slightest doubt Danny wasn't ready - either mentally or physically - then I wouldn't be considering him.
"It's not as if he's just trained for a week and had one reserve game. He has been training with us for the last three weeks.
"The medical people have done a fantastic job with him. He's an athlete and he's naturally fit. Also he's one of those players who isn't fazed by anything.
"In a perfect world I'd like to give Danny a bit more time but circumstances alter things."
"I watched a video of the game on Sunday - which I don't normally do - and there was plenty for me to think about.
"We didn't defend well at all. It would be easy to give Danny more time but sometimes I have to follow my instincts.
"I could play Danny in six reserve games but he will only do in those games what he has to do.
"The tempo and pace of a training session can be better than what he gets out of a reserve game. Also Danny has got to make the jump to the first team at some point.
"I understand that I must speak to the medical people about playing Danny. Then there's the boy himself to consider."
After unconfirmed rumours overnight about Danny's chances of playing it appears he has travelled to Wycombe and could be in line for a start against the Chairboys. Gabbidon last played a league game in November 2002 when he was injured at Barnsley. Since then he has only played 60 mins of reserve team action.Alan Mahon is carrying a knock and could be a doubt. Andy Legg could replace the on loan left winger.
One thing is for sure, Martyn Margetson will keep his place as Alexander is still injured. It will be Margetson's third league start of the season and his second against Wycombe.
City play the last game in hand on Crewe and only a win will be acceptable. Three points will put the City back into third place and only one point behind Crewe. Then it's a 6 match race for the second promotion place.
Wycombe suffered a 4 - 1 reverse at home on Saturday to Stockport, the Chairboys were 1 up against the run of play on 65 mins but capitulated and conceded four goals in the last 12 minutes.
A big score would be nice but a win is vital, whatever the score.
