Former Wigan defender Markus Holgersson is attracting interest from three Championship clubs, Sky Sports understands.
The Swedish defender is a free agent after signing on a short-term deal for the Latics in February.
After making one substitute appearance during his spell at the DW Stadium, Wigan boss Uwe Rosler has opted against offering the Swede a contract.
His availability has alerted Charlton Athletic, Huddersfield Town and Birmingham City, who will battle it out for Holgersson's signature.
The 29-year-old has one cap for Sweden and featured heavily for New York Red Bulls before his switch to Lancashire.
