Auburn cornerbacks Kamryn Melton and Joe Turner, as well as safety Derrick Moncreif, have announced they are leaving the program, according to the Montgomery Advertiser.
The announcements, which all came during a 36-hour span on Thursday and Friday, raised to five the number of non-graduating defenders who have left the program over the offseason.
The departures leave Auburn with only nine scholarship players in its entire secondary and only five scholarship players at corner, according to the Advertiser.
"Kamryn, Derrick and Joe have decided to transfer and purse playing opportunities elsewhere,' Malzahn said. "We thank them for their time at Auburn and wish them well in the future."
Moncreif, a rising senior, had 27 tackles, one pass deflection and one forced fumble for the Tigers during the 2014-15 season.
Melton, a former three-star recruit from Dothan, Ala., who will have three years of eligibility remaining, did not appear in a game last season. He played in three games in 2013 before suffering a knee injury.
"I want to thank Coach Malzahn and the Auburn coaching staff for giving me the opportunity to attend and play football for such a prestigious school," Melton tweeted.
"I also want to thank the Auburn family and fans for the life-long memories I made while I was on The Plains. In my heart I will always be a Auburn man, but after praying and having a discussion with my family I have decided to transfer."
Turner had transferred to Auburn from the College of San Mateo (Calif.), had not appeared in a game for the Tigers.
Auburn hired former Florida head coach Will Muschamp as its defensive coordinator in December.
