The Union have brought in 6-foot-4 Polish striker Kacper Przybylko for a tryout, with an eye on boosting the team's attacking depth in the midst of the playoff race.
Przybylko, 25, most recently played for German second-division club Kaiserslautern, though he only got into one game last season. His best scoring season came in 2015-16, his first year at Kaiserslautern, when he had seven goals and one assist in 30 games. In the 2014-15 season, he had five goals and four assists in 32 games for Greuther Fürth, also in Germany's second division.
He was a Polish youth national team prospect at one point, up to the under-21 level, but has never made the cut for the senior team.
