HOUSTON — The family of a former Rice University football player who died during a workout has settled its lawsuit with the school and the NCAA, which has agreed to recommend that its member universities test all student athletes for sickle cell trait.

Dale Lloyd II died a day after he collapsed during a conditioning workout Sept. 24, 2006. The 19-year-old freshman's death was linked to sickle-cell trait and created the basis for the lawsuit filed in state district court in Harris County.

Much of the settlement is confidential, Houston television station KRIV reported Sunday night.

An NCAA spokesman said many of its schools already do the testing, and that the association can only recommend that schools do it — not mandate it.
