Do you start him or bring him in as a sub to play 20 mins? You start him, because if he pulls a Costa and re-injures himself, it only burns one sub, as opposed to subbing him on and then having to bring him right back off. Or worse, if he's the 3rd sub and re-injures himself, then we're down to 10 men. For me, he either starts, or doesn't play at all. I'm kind of proud that this was the strategy I was thinking about being the best.
