Lincoln City may turn to former Chesterfield centre-back Dan Gray and ex-Imp Graham Hutchison to add much-needed cover to their defence.
The Imps have taken the duo on trial with both players due to be given a run out in last night's friendly against Worksop, writes Leigh Curtis.
Lincoln are desperately searching for a new defender after Ashley Westwood left the club fewer than 50 days after arriving to pursue a coaching role with Portsmouth.
After moves for Exodus Geohagon and John Dempster fell through because of a lack of funds, Holdsworth is exploring every avenue available to fill the void.
But after admitting experience comes at a price, Holdsworth may be forced to pursue cheaper and younger options.
And he says he has been impressed with 19-year-old Hutchison and 22-year-old Gray's contribution so far.
"It has been well documented that we are looking for cover in that area," he said.
"Dan has played a lot of games for Chesterfield and can play centre-back, centre midfield or right-back.
"Graham plays in the heart of the defence and I must say, I have been really impressed with what I have seen so far.
"They have trained very well and given a good account of themselves in the time they have been here.
"Both players have settled in quickly which is always a good sign, so we will just have to wait and see what happens."
Hutchison was sold to Birmingham by Lincoln in a deal believed to be worth £35,000 two years ago.
The Scot has just signed a professional contract with the Championship club, who may loan him out to gain some much-needed experience.
The Scottish youth international is tipped to have a bright future and Holdsworth may look to exploit his relationship with the Blues having played for them during his career.
Gray, meanwhile, has played 45 games for Chesterfield, but was released at the end of the season. He has also had loan spells at Macclesfield and Alfreton.
