Blackburn Rovers have reportedly granted Nuno Henrique permission to depart the club.
The 27-year-old joined Rovers from Academica in 2012, but he has failed to make an appearance for the senior side.
As a result, both parties have agreed that the defender can leave Ewood Park, with CSKA Sofia in Bulgaria his most likely destination, according to the Lancashire Evening Telegraph.
Henrique has spent part of the current campaign with Portuguese outfit Arouca on a loan deal.
