The win pushed the Reds up to 11th in the table and just four points off the play-offs.
Nichols was the matchwinner but who else stood out for the Reds?
Here are GH Away Day travel's player ratings.
.
Crawley Town at Northampton Town
. Glenn Morris 8
Was again on his tip top form and made a great save at the end to keep a clean sheet to earn the 3 points
. James Tilley 7
Again another faultless display - playing now as a wing back - did his defensive duties brilliantly
. Ludwig Francillette 8
Another solid performance, forming part of a great trio at the back in the new formation, pick up an injury at the end but hopefully not to serious
. Tony Craig 9
Another outstanding game, reads everything so well and didn't let anything distract him from his game - "Man of the match" as voted on the coach
