This will be the second stint with the Fire for Soumare, who is expected to be available Saturday at Real Salt Lake.
He was chosen with the second overall pick in the 2007 SuperDraft and spent three seasons with the Fire before transferring to French First Division team Boulogne in August 2009.
In January 2012, he was loaned to German club Karlsruher SC, and he signed with the Union on June 26, 2012 after they traded with the Vancouver Whitecaps FC to move up in the MLS Allocation order.
Soumare started all four matches he appeared in for Philadelphia.
