Back on the first weekend in September, a Well side playing at the peak of their powers trounced Terry Butcher's side 4-1 at Fir Park.
But since that mauling the fortunes of the two sides have gone in different directions.
Butcher's boys have gone on a 10-game unbeaten run that has seen them move fourth in the SPL and knock Rangers out of the Scottish Communities League Cup at Ibrox.
By contrast, Well have won just two of their last nine games and have dropped to seventh place in the top flight table which has left the Fir Park club's talented young stopper preparing himself for a Highland charge to revive their fortunes on Sunday.
Cummins said: "We are under no illusions that Inverness will be well fired up for us on Sunday. The last time we met we probably turned in our best performance of the season to beat them 4-1 at Fir Park and they will most certainly be out to avenge that.
"When you look at the run they have been on then they have really shown a lot of consistency and I think the big thing with them is that they are very well organised and physically a very strong side across the park.
"So if we want anything from this game then we are going to have to match them across the field, win our battles and then look to play football.
"But by the same token they will know that if we click we can give them some real trouble after that last game. So I think it is fair to say that both sides will be wary of each other."
Well's home form has proved to be a frustration, with just one point taken from the double header with both Dundee sides last week.
However, Stuart McCall's men have lost just once on the road from six trips this term, going down 1-0 to Hearts last month.
That is a statistic the Steelmen star has taken great encouragement from ahead of their trip up to Inverness.
The 19-year-old said: "We have been to some difficult places like St Johnstone where we ended their unbeaten run and Aberdeen when we were pegged back for a draw at the last minute.
"We can take a lot of positives from these games ahead of Sunday.
"Our away form has been good and if we can produce the type of football we did at St Johnstone a fortnight back we will give ourselves a real chance to get the result we need.
"Whatever way you look at it this match is huge for both sides."
