The chance for a fourth national championship in five years has taken a dramatic hit.

The Florida State men's track team, which won three straight national titles from 2006 to 2008 and finished second in 2009, has lost the services of star sprinter Charles Clark for the remainder of the year.

Clark, a senior, tore his quadriceps in practice before the ACC Championships and will be out "four to six months," according to the FSU sprints coach Ken Harnden.
