I looked through known issues and didn't see this. In my last match, my opponent started the match with only 3 players, obviously the 2 spaces were taken by lucky fans but they didn't appear as such, whenever one of them did something in the game, it just left a blank gap instead of a name, and same the stats box.
Same happened to that team in the first play-off round, he only had 4 players and an empty gap that he started with, one of the players got injured and the lucky fan came out in his place. So he finished the game with 1 empty space that was getting rebounds and etc and a lucky fan.
