Having gone through the rules I would say Thrud is not allowed on 2 counts:
1) It says LRB applies unless specifically stated below and then further down under Star Players says You may only use the official Star Players from the list on the back of the Blood Bowl Handbook.
2) It states under Star Players that they cost the full price on the card and are not freebooted as this is not a league.
Prepared to risk it and face a yellow card (-5 points) for an illegal roster ?
Not I.
Not that I'd take him anyway.
