Injury replacement
 

So this happened last week:
Time-out is called for an injured B11. While B11 is being attended to by trainers, another team attendant (we found out later it was a water-girl, not a trainer) comes out onto the field and helps B24 stretch his calf muscle.

B11 obviously needs to be removed for 1 down, does B24 need to be removed also?

EDIT: Meant to post this in the FB forum... mods feel free to delete this thread.

I know if an opposing player is also injured that team must take a TO to keep him in. However for multiple players on one team I am fairly certain 1 TO would suffice. I have to get to my book and verify this.
