North Wales Crusaders came agonisingly close to victory at Rochdale Hornets, as Tommy Johnson's missed conversion at the death saw them lose 19-18.
Rob Massam collected Andy Moulsdale's grubber to go over in the final minute for the injury-hit Crusaders, but Johnson sliced the following kick wide.
Both sides finished with 12 men after Scott Turner was sent-off along with Hornets' Dale Bloomfield for fighting.
South Wales Scorpions were beaten 48-10 at home by 12-man Keighley Cougars.
The visitors had former Scorpion Samir Tahraoui sent off in the 36th-minute for throwing a punch, but were still far too good for South Wales as they ran in 10 tries - including hat-tricks for Josh Guzdek, Paul White and Andy Gabriel.
