TOWN will have untried 17-year-old goalkeeper Simon Eastwood on the bench at Chesterfield tomorrow after loaning Paul Rachubka to League II club Peterborough.
Posh, who host Lincoln, have borrowed former Manchester United man Rachubka for seven days, the maximum time allowed because the loan deadline has passed and the transfer window has yet to reopen.
While there can be no moves for outfield players, keepers are considered a special case under League rules, and London Road chief Keith Alexander is without both Mark Tyler and Luke McShane through injury.
But Town have a recall facility should first choice stopper Matt Glennon be injured or sent off (a red card at Chesterfield would rule him out at home to Tranmere on Boxing Day, when Peterborough go to Barnet).
Jackson, who has made summer signing Glennon his first choice this season, explained: "Barry Fry (Peterborough's director of football) rang up and explained their current predicament.
"This is a way of helping them out and also getting Rabs some first-team games, which is important given our lack of Reserve matches recently (the last was on November 28).
"The recall facility means that if we have any problem over Matt's availability, we can get Rabs back for the Tranmere game."
Rachubka, who had a loan spell at Town from Charlton during 2003-04 and made the move permanent at the end of that campaign, has made just one first-team appearance this season.
That was as a substitute in the 2-1 home defeat by Doncaster in the first round of the Johnstone's Paint Trophy, when Glennon suffered an injury.
Eastwood, who has been capped by England at junior level, has twice been on the bench before - at home to Oldham and away to Bournemouth last season.
"Simon is a top prospect and I'll have no worries about using him if needed," said Jackson.
Town fans can pay at the gate tomorrow, although tickets can be bought in advance.
