The 24-year old is looking to get back into a regular playing environment after recovering from extensive injuries he sustained in a car accident back in October 2009.
Davies has not played for the French Ligue 1 outfit since before the accident occurred and is seeking a loan to Washington-based DC according to a statement releaed by the club.
"Charlie Davies is expected to join D.C. United in Ft. Lauderdale on Wednesday for a week-long evaluation period, which will include training and game time with the first team and a full medical evaluation by team doctors in DC," the statement read.
"Details of a 12-month loan have already been negotiated, but nothing will be official until D.C. United is satisfied he is physically capable of playing at the level required to be successful in MLS. United currently holds the top spot in the League's allocation ranking and would therefore have first option to acquire Davies."
