GIANT prop Jamie Fielden burst onto the Cougar scene with a spectacular opening performance against Oldham.

The 6ft 6ins forward, who weighs in at 20-stone, scored his opening try for the club after being on the field for less than three minutes. Even earlier he had shown his tremendous promise by forcing his way 10 metres upfield as he drove a string of defenders backwards.

Jamie, the brother of Great Britain and Bulls forward, Stuart Fielden, was a member of the Bulls Academy before moving to Huddersfield and Doncaster, where he enjoyed his best years. But he moved to Keighley following a dispute with the South Yorkshire club.

He will return to Doncaster's Belle Vue stadium on Sunday as a key member of Moorby's squad -- and determined to produce a top performance against his former team mates.

Last weekend the Keighley side came agonisingly close to snatching victory against Oldham, but are still fighting it out at the bottom of the LHF National League division one.

Moorby said: "We are our own worst enemies, we scored 28 points at home and still managed to lose by five points. We had several chances to score more tries but took the wrong options.

"We were caught three times by quick restarts, but we should never have given them the opportunity to take a 20-metre tap in the first place. Poor last play options gave them the chance to play quickly on us and it is very hard to defend against.

"I know it must be frustrating for the supporters but believe me no one is more frustrated than the coaching staff when instructions are not followed by certain individuals and ultimately this is costing us dearly.

"I firmly believe we are capable of achieving in this division, however we need to smarten up quickly.

"We have a tough game this weekend at Doncaster and I believe that if we play smarter we can do well."

The game against Doncaster, who are currently just two points behind league leaders Whitehaven, is sure to be an action-packed encounter, but the Cougars are once again fighting against injuries.

Karl Smith injured his knee last weekend and looks very doubtful for Sunday.

Chris Wainwright is likely to be recalled into the 17-man squad while Lee Patterson came through the game unscathed on his return from injury and will be in the line-up.

Doncaster coach St John Ellis could also add youngsters Wayne Green and Tom Buckingham to his squad if they perform well in an Academy game, and forward Matt Walker is expected to return to after a two-match ban.

But the Dragons look set to lose centre Gareth Lloyd, who suffered a facial injury in an accident at work. He needed more than 70 stitches in his face and could well retire from the game.

Moorby, who is close to signing 20-year-old second row forward Dean Noble, son of Bradford Northern and Great Britain coach Brian, who has played with the Cougar Academy team in recent weeks.

"He has a good pedigree and has enough Super League experience to do a good job with Keighley," said Moorby.

He is also giving trials to Siddal winger Steve Hope.
