LATICS LAND MIDFIELD DUO
25-year-old Bukran has signed on a non-contract basis, after impressing manager Paul Jewell during a week-long trial, following his release by Walsall.
Adamczuk, meanwhile, has agreed a three-month loan deal, with a view to a permanent deal.
The 31-year-old is sure to add a great deal of quality to the Wigan midfield as only last year he was playing in the Champions League,
"He's a very fit lad who can get up and down well," said Jewell of Adamczuk.
"He will fit in on the right hand side of the team and bring us a bit more balance. It's a deal that will suit all parties down to the ground and gives us a chance to have a good look at him."
Both players go straight into the squad to face Brentford at the JJB Stadium on Saturday.
