Brian Davis, Parade Magazine's 1984 national high school football player of the year, has enrolled at Montgomery-Rockville, but has been ruled ineligible this season.
The former Washington (Pa.) High School scholastic all-America running back originally enrolled at Pittsburgh, making his debut by rushing for 100 yards in the second half of Pitt's 29-22 loss to Boston College in 1985. He was suspended for one year in January because of academic troubles.
Montgomery Coach Phil Martin said Davis needed 24 credit hours with a 1.75 grade point average in order to be eligible this season, but could transfer only 16 hours from Pitt.
Davis has told Pitt officials he would like to return in 1988.
