At Bat Batter ejected - What's the count?

[officialtony]

Varsity FED game. I am BU. B1 1st at bat hits a single and sends his bat past the ear of PU as he releases it. B1 is now R1. PU calls time and warns R1 and coach if R1 throws bat again, R1 wil be ejected. 3rd inning, same B1 comes to plate. With a 2-1 count, B1 hits a long foul ball and the bat hits PU in the foot as he lets it go to run. PU tosses B1 and tells coach to get a batter in to replace B1 who has been ejected. Does B2 ( the replacement batter )assume the count of 2-2 that was on the ejected B1? That is what the PU did. I was not consulted. I would like to know if that is the case, what FED rule supports that theory.

Thanks in advance.
