Derek Adams said Yann Songo’s red card had a major bearing on the Shrimps’ home defeat to Tranmere.
Morecambe looked the more dangerous side until Songo’o saw red just before the break and Tranmere took advantage of the extra man in the second period.
Adams said: “I don’t know what happened with the red card and we will have to wait and see what the report is.
“The referee didn’t say anything, the fourth official didn’t say anything, so we will have to wait and see.
“But it did give Tranmere the advantage. Before then were in command. We pressed Tranmere all over the pitch and caused them a lot of trouble. We were unlucky to have a goal disallowed and then we missed a penalty and had Yann sent off.
“That was always going to make it difficult for us in the second half and it gave the advantage to Tranmere.
"It was the break they needed on the day because we were the team that were on top in the match and were controlling it and to lose one of our most important players made it tough and gave us an uphill struggle.''
We looked like we were going to go and win the game but, unfortunately, one of our most important players gets sent off and it gives us an uphill struggle.''
