Castleford head coach Daryl Powell criticised his team’s lack of composure after they failed to see off 12-man Hull FC on Sunday.
Hull were 18 points ahead when Liam Watts was dismissed for flattening Luke Gale in the 22nd minute, but the Tigers were unable to pull back the deficit as they were defeated 26-24.
Powell said: “It was still doable, but we panicked – Hull were superb and started like a house on fire and we were nowhere to be seen, which was disappointing.
“When they went down to twelve men, we spoke about being calm – but they kept us out. I’m not taking anything away from Hull as it was a tremendous effort.
“To lose Gale was a blow and we lost some clarity as we couldn’t get our combinations together and we made too many errors.”
