The school announced the NCAA's decisions Monday.
Both players suffered season-ending injuries in August. Brown, a linebacker, tore his left anterior cruciate ligament on Aug. 11 while Deaver, a tight end, tore his right ACL a week later.
Both players also missed the 2012 season due to injuries.
Brown was an all-Atlantic Coast Conference linebacker in 2013 while Deaver caught multiple passes in every game during the Blue Devils' run to the Coastal Division title, ACC championship game and Chick-fil-A Bowl.
