Fed: 0 players from team B on field

[HLin NC]

Actually you would have a violation of 3-6-3:
ART. 3 . . . Failure of a team to play within two minutes after being ordered to
do so by the referee.
PENALTY: (Art. 3) – forfeiture

Team B might not care but I'm sure Team A will get the other 10 out there.

It might be simpler just to invoke 3-1-3 and skip the free kick down.

ART. 3 . . . A period or periods may be shortened in any emergency by agreement of the opposing coaches and the referee. By mutual agreement of the opposing coaches and the referee, any remaining period may be shortened at any time or the game terminated.
