I think it goes in cycles where they hit certain teams with lots of injuries or suspensions.

At the start of this season I was getting at least a player sent off or injured each game and on several occasions had 3 or 4 happen per game. At one point I had 6 players suspended with 5 injured. To stop the game from awarding 3-0's against me I had to work out which players were suspended for what games and heal some players so I had enough players to play the game. Thankfully I had a few hundred red tokens, otherwise I'd have been screwed.
