Birmingham were 7-6 up when the brutality exclusion occurred. Bridgefield missed the resulting penalty but soon led 8-7 with goals by Liam McCarthy and Andrew Faulkner. That's how it stayed - until the last 10 seconds. Then Bridgefield conceded a penalty, comfortably converted for an equaliser by the outstanding Drazen Videc, Birmingham's top marksman with four.
York City recovered from 10-9 down to beat Hucknall 13-11 courtesy of final quarter goals by Ben Pacey, Chris Burns and Danny Rippon.
Tyldesley made it three wins out of three, outplaying Caledonia Storm 21-6. Matt Hannah scored seven for Coventry against Rotherham - but still ended up on the losing side. Rotherham's 14-11 success included half a dozen strikes by Dan Hunt.
Bridgefield drew for a second time late on day two - 10-10 against York City. York were 10-8 down near the end but equalised with goals by Ben Pacey and - with 38 seconds left - Will Tomlinson.
