Francis Cummins was facing further injury woe last night as the Bulls crashed to a 46-6 home defeat the hands of arch-rivals Leeds.

Matty Blythe sustained a potentially serious knee injury and will undergo a scan, while James Donaldson (ankle), Adam Sidlow (back) and Lee Gaskell (ankle) also picked up knocks.

Head coach Cummins said: “Until Matty has the scan, we don’t know how serious it is, but it could be bad.

“James Donaldson did his ankle, Adam Sidlow took a bang in the back and stiffened up and Lee Gaskell also did his ankle.

“For a long time we only had one sub and in the end we didn’t have any.

“That was difficult but it’s still a frustrating time because we are miles better than we are showing.”

Cummins was already missing winger Jamie Foster and captain Matt Diskin through illness and a calf injury respectively last night.

Foster should return in Monday’s trip to Wigan but Diskin is expected to remain sidelined and Cummins will nervously await the prognosis on the quartet struck down against Leeds.

The Bradford boss was left frustrated for the second week running as his side were caught napping during an awful opening quarter.

The hosts barely escaped their own half during a first 15 minutes which saw the Rhinos score four tries to establish a 20-0 lead.

Cummins said: “I thought Leeds started very well but we only had the ball for two sets in the first 14 minutes.

“Against a team like Leeds, you can’t do that. We clawed our way into a situation where we got into the game but we’re not having enough pressure on the opposition’s line.

“When we do, we look like a team who haven’t been down there for a long time. We’re not building any pressure and our game sense is not good enough.

“Having said that, we lost a couple of players early who weren’t going to return – but there were silly offloads. You finally force a repeat set and then you make an error on play one.”

Cummins bemoaned his side’s luck as Ryan Hall scored a hat-trick of tries and added: “You do get the feeling that if something can go wrong, it’s going wrong at the moment, but we’ve got to be better.

“There are certain areas of our game where we work hard but ultimately we are letting each other down.

“People are chasing after they have made an error and then we are getting into situations where we are just panicking.

“If we were a basket case then I could accept that but we’re not – we’ve got some good players.

“We’re down on numbers but we’re not playing anywhere near our potential and that’s frustrating.”
