Jacobs was on the scoresheet on his first league start since April, as Danny Cowley’s men picked up a 2-1 win over the Dons.
The 30-year-old missed a great early chance when put through by Marcus Harness, and opted for a cutback to George Hirst which saw another opportunity not taken.
Jacobs levelled things up when put through in the 63rd minute before Harness won it late on.
He said: ‘When you’ve not played for a long time and get into those positions you’re sometimes a bit rusty.
‘I got stuck in two minds whether to lift or not. It was a great touch from Marcus, but maybe I had too much time.
‘Then there was the one for Hirsty, I maybe should have put a bit more on it.
‘Then we went 1-0 down and it was difficult, but I felt I’d get another chance and I just took the shot on and was glad to see it go in.’
