The injury to Danny Hone has caused a crisis across the back, and Jacko has confirmed he'd like to bring Bencherif back to the Bank for a second spell.
He is hoping to tempt the giant Algerian back to Sincil Bank to fill the gap left by Danny Hone, who's injury looks likely to keep him out until early April.
The 19-year-old is suspected to have damaged ligaments in his right knee during Saturday's 2-2 draw against Rochdale and will soon be going for a scan to assess the damage.
His absence coupled with Sinclairs shocking form and Paul Greens suspension means City are fragile across the back entering a crucial period of the season.
Bencherif was transfer listed in December by Colin Calderwood, but whether Billy Davies feels the same remains to be seen.
"I've made an enquiry about Hamza regarding the possibility of him coming here on loan" said Jackson.
"But it all depends on Billy Davies because he hasn't had the opportunity to see him play yet since taking charge.
"Obviously, Danny's injury has left us a bit short so it's just a case of seeking cover. The advantage with Hamza is that he knows Lincoln well, but we'll just have to wait and see what happens."
The other option is trialist Moses Swaibu, due to play for the reserves this afternoon.
