Subs for Injured Players

What happens if your left or right fielder goes down and you only have a cf on the bench? I’m assuming if the cf is the only other outfielder, HAL will put him in. My question is really about what happens to the fielding rating. I think the rules in the board game say that a cf’s fielding rating stays the same if he’s put in left or right, since cf is the most demanding outfield position.

Also, I think the game rules say that if a similar thing happens in the infield, a shortstop moving to second or even third will keep his shortstop rating if you have to plug him into those spots because you don’t have another shortstop or third basemen.

However, if you have to move a second or third baseman to short because of injury and having not other second or third baseman - or a left or right fielder to center, - think the rules say their defensive rating gets worse.

Hope what I’m getting at is clear.

Thanks.
