Delete exhibition games?
 

I was running an exhibition game as a test for a fictional league of mine and I intended for the stats to not be reflected on the players, however I see that the results of the exhibition game have been reflected on the players stats and I wanna find a way to delete the exhibition games that I held. Is there a way to do that?

correction: I mean the exhibition games remain in the League Home tab, so I wanna find a way to remove them in order to keep the league like it hasn't played any games
