Block When a Both Down result is applied during a Block action, this player may choose to ignore it and not be Knocked Down, as described on page 57.
Thick Skull When an Injury roll is made against this player (even if this player is Prone, Stunned or has lost their Tackle Zone), they can only be KO’d on a roll of 9, and will treat a roll of 8 as a Stunned result. If this player also has the Stunty trait, they can only be KO’d on a roll of 8, and will treat a roll of 7 as a Stunned result. All other results are unaffected.
