The Green Bay Packers have signed an undrafted cornerback after he tried out last month during minicamp. Daquan Holmes played at American International and was named first-term Northeast-10 All Conference in his junior and senior seasons.  The five-foot-11, 187-pound defensive back intercepted five passes his senior season.  He also returned two kicks for touchdowns during his career.  At the same time they signed Holmes, the Packers waived David Rivers with an injury designation.
