The 23-year-old was recently made a free agent following his release by Jagiellonia Bialystok.
However, he has now been handed the chance to earn himself a contract with the Berkshire-based outfit, according to the Reading Post.
Slowik, who has been capped on one occasion at senior international level, is expected to spend two days with the Royals.
