Background and college
Born March 20, 1985 in Fayetteville, North Carolina, Murrell attended Jack Britt High School in Fayetteville, NC, where he registered 21 sacks over his final two seasons to earn All-Region honors. He was a two-time first team All-American performer at Appalachian State University, finishing his career with 36 sacks and a school-record 18 forced fumbles. Murrell gained 13 sacks in both his junior and senior seasons, fueling his Appalachian State to two consecutive Division I-AA National Championships in 2005 and 2006. In the 2005 title game he forced a key fumble that was returned by Jason Hunter for the winning touchdown in a 21-16 victory over University of Northern Iowa.
Before the Jets
Murrell was originally signed by the Philadelphia Eagles as an undrafted free agent in 2007. In a preseason game he had two sacks and two forced fumbles against the Jets. However, the Eagles waived him after the preseason, but signed him to their practice squad.
As a Jet
In November 2007, Murrell was signed by the Jets. Murrell played in four of the Jets' final seven games of the season, but did not record any stats. In 2008, Murrell made the Jets' 53-man roster and played in 12 games as a reserve, recording nine tackles.
In 16-13 overtime loss to the Buffalo Bills on October 18, 2009, Murrell and Jets safety James Ihedigbo threw punches at Bills tight end Derek Fine, prompting Murrell to be fined by the NFL for $5,000 and be benched, along with Ihedigbo, by head coach Rex Ryan for the following game against the Oakland Raiders on October 25, 2009. Murrell finished the 2009 season with 12 tackles in ten games played. He was not tendered by the Jets as an restricted free agent following the season and became an unrestricted free agent.
After the Jets
Murrell is the younger brother of running back Adrian Murrell, who played with the Jets from 1993 to 1997.
