Need a rule referance and ruling, I can't find one.

[Steven Tyler]

The key word is ejected, not substituted. I would have to believe this wouldn't be allowed as the rule is written. In MLB, you cannot do the double switch with players in the line up. Take for example. Last batter of the seventh is called out on strikes, argues and gets thrown out of the game. The manager wants to bring in a reliever and put him in the spot that player got ejected and put a position player in the pitcher's spot so he won't have to waste a pitcher or a pinch hitter. It is not allowed. You must substitute only for the player who is ejected.

A substitute for an ejection is totally different than an a substitution for a player.
