Done the lad a favour actually, looked like he wasn't going to leave the field & kick off a bit more. He could have no complaints, it's a clear red card but he's a young player who has tried to make a name for himself with crunching tackles. He got what he deserved - if Doyle hadn't anticipated it he could have been seriously injured.
To be fair the same could be said of the Blackpool highlights and us. Its almost as if they ignore the game and just try and stick 3 chances for each team in them.
