CLEVELAND (AP) _ A former Cleveland Browns' quarterback convicted of defrauding the welfare system at his dental office has been released on $100,000 bond to await his appeal.

Dr. David W. Mays of Shaker Heights was convicted of welfare fraud in May. Mays was convicted on 36 felony counts in a scheme in which he billed Cuyahoga County $2.7 million for dental procedures he never performed.

Judge Patrick Kelly sentenced Mays, who played for the Browns in 1976-77, to five to 15 years in prison, then declined to set an appeal bond because he said Mays might run away with the money he was convicted of stealing.
