He was a two-time All-District and All-State wide receiver and defensive back at UIL Class AA.

[2] On December 7, 2018, Davis graduated from Sam Houston State University with a Bachelor of Science in Kinesiology degree.

[3] Davis was signed as an undrafted free agent by the Dallas Cowboys after the 2002 NFL draft.

In 2003, before the start of training camp, he was shot in the right hip and left elbow around 2:20 a.m. outside the Dallas Gentlemen's Club.

The friend was sitting at a table where an altercation broke out, and spilled outside to the parking lot, culminating with his shooting while defending his girlfriend.

While he did nothing to provoke the incident, and was regarded as an unwitting victim, head coach Bill Parcells believed Davis should not have placed himself in a questionable situation and released him from the team on July 26.

On January 13, 2004, he rejoined the club after Parcells gave him a second chance, re-signing him to play in NFL Europe.

Davis took advantage of the opportunity and was named All-league, while helping the Berlin Thunder to the World Bowl XII championship.

This time he was randomly shot in the back of the head and in his right thigh, while driving to church at 5:30 a.m. on a Dallas freeway.

On March 11, 2008, Davis signed as an unrestricted free agent with the Miami Dolphins, reuniting him with team vice president Bill Parcells.

He also received the Ed Block Courage Award for playing with a torn pectoral muscle.

On May 21, 2009, the Oakland Raiders signed him as a free agent to add depth at the safety position.
