Dallas Cowboys

Holloman was drafted in the 6th round (185th overall) of the 2013 NFL Draft by the Dallas Cowboys. During the preseason he showed a knack for creating turnovers, returning a 75-yard interception for a touchdown in the Pro Football Hall of Fame game against the Miami Dolphins.

After being the backup for Justin Durant during the first 6 games, he missed seven games while recovering from a spine contusion he suffered in practice. Holloman returned to play in the 15th game of the season against the Green Bay Packers, with the Cowboys forced to start him at middle linebacker because of injuries, even though he had never played the position before. He would start three games, with his best production coming in the season finale against the Philadelphia Eagles, leading the team with 11 tackles and 2 sacks.

During the preseason game against the Baltimore Ravens on August 16, 2014, Holloman's neck was injured (his second neck injury playing football) in the fourth quarter. After visiting with doctors, he was subsequently diagnosed with a narrow spinal column condition (cervical spinal stenosis), which forced him to announce his early retirement on August 25.
