FORMER EAGLES fullback Kevin Turner said he joined a lawsuit filed Thursday in federal district court here by former National Football League players and their families against the NFL because he wants to make sure former, current and future players receive adequate medical testing and monitoring of football-related head injuries before they become life-threatening. Turner, 43, who lives in Birmingham, Ala., has been diagnosed with Amyotrophic Lateral Sclerosis, or ALS. He believes it may have something to do with all the hits he made and took during his eight seasons in the NFL, the last five of which were spent with the Eagles. He retired from the NFL in 1999.
