Jermarcus joined the Lions as a free agent shortly after the season started as injuries mounted on the club’s offensive line. Showing early promise at the tackle position, he appeared in four games including his CFL debut on Jul 19/14 versus Montreal before suffering a leg injury that sidelined him for three games. He returned to the line-up for the remainder of the season at the left guard position ultimately appearing in 12 regular season games, 10 as a starter.
2010-2011: Enjoyed a notable two-year career with the Huskers, playing in 27 games at left tackle and securing the starting position in his senior year. In 2011, he helped Nebraska to back-to-back 300-yard rushing games and lifted the offence to 217.2 rushing yards per game, good enough for 15th in the nation. The Huskers rolled for 200+ yards rushing seven times in the 2011 season including three games with 300+ yards on the ground, and a season-high 346 yards against Minnesota. 2008-2009: He helped the Fort Scott CC Greyhounds to an 11-1 record in 2009 and a national runner-up finish. Jemarcus was a key figure for an offense that averaged better than 30 points per game and led the Jayhawk Conference in total offense, averaging more than 420 yards per game. He was a first-team all-conference pick in 2009, as well as an All-Region VI pick. As a freshman, Jemarcus was a second-team All-Jayhawk Conference pick.
