The 28-year old, who has also enjoyed recent stints with Al-Ettifaq and FC Gueugnon, is one of four trialists being monitored by the Fire this past week, being joined by French midfielder Malaury Martin, Mexican defender Victor Perales, Cameroonian midfielder Mba Adek and a Serbian player.
Fire technical director Frank Klopas said it was a great chance to see if the club could bring in some quality beginning with White.
"He was playing over in Denmark for years," Klopas said. "[He's] just a guy that's got a lot of pace and can play different positions.
"Everybody brings something different, but I think we're looking at some different options and just got to see how they fit in. There are some good quality players here."
