MANAGER Peter Jackson is confident Jon Worthington will lead by example in tomorrow's away-day points raid on Peterborough (3.00).

The 21-year-old skipper scored the winner against Sheffield Wednesday and is now keen to steer Town to a fourth straight win in front of more than 1,000 travelling fans at London Road.

Town are also targeting a third successive clean sheet for the first time in Jackson's 193-match managerial career, although keeper Paul Rachubka missed training yesterday with a back strain and was being checked out.

"The lads are straining at the leash because of the excellent run we're on and, if we keep it tight tomorrow and play like we can, we will win," said Jackson today.

"Another clean sheet would be great, but we are going down there positively and we'll be looking to pick up where we left off.

"I thought Worthington had his best game of the season against Wednesday and it was great for him to get the winner, because he should score more goals than he has been doing.

"What impressed me most was his tackling, because his timing was good, his energy levels were good and his passing was good.

"It was a typical captain's performance. For a young man, he has taken that responsibility well.

"He organises the players and they respond, because they look up to him. He is our leader both on and off the pitch and no-one will be fired-up more to win tomorrow than Worthy."

Jackson is keeping team plans under wraps against Barry Fry's second-bottom side, which could include former Town loan player Fola Onibuje.

Nathan Clarke is available after suspension as Town bid to complete a double over Posh, while Tony Carss and Steve Yates are again ruled out through injury.

"Peterborough know how well we can play and we don't want to let them down," added Jackson.

"They will be fighting for their lives and we need to match them."

Striker Andy Booth is again after the goal which will take him to 109 in Town colours and to fourth place in their all-time list of top scorers ahead of Les Massie.
