BUFFALO, N.Y. (AP) Buffalo Bills coach Rex Ryan is giving a second chance to a former colleague by hiring John Blake to become the team's defensive line coach.
The Bills announced that Blake had agreed to terms on Tuesday, two days after Karl Dunbar was abruptly fired.
Ryan was Oklahoma's defensive coordinator in 1988 during Blake's final year as Sooners head coach.
Blake had been hired last month to be a defensive line coach at Lamar University in Texas. He had been out of football since September 2010, when Blake resigned as North Carolina's associate head coach as a result of an NCAA investigation.
In 2012, the NCAA ruled Blake received personal loans from a sports agent while coaching.
Blake won two Super Bowls coaching the Dallas Cowboys defensive line from 1993-95.
