Detroit Lions safety Louis Delmas missed Friday’s practice session, but has not been ruled out for tomorrow’s game at Philadelphia. Delmas is hoping to play for the first time this season following knee surgery in August. Detroit coach Jim Schwartz said yesterday the team is still waiting for the results from running back Jahvid Best's latest concussion test. Best has not played since last October because of post-concussion symptoms. Live coverage of Lion’s football on AM 1590 and FM 95.5 begins at Noon tomorrow from Philadelphia.
