After playing college football for the Tulsa Golden Hurricane, he was signed by the Philadelphia Eagles as an undrafted free agent in 2012.

According to Johnson, his first cousin Mark Young acted as a surrogate father and taught him how to play football.

He eventually became the all-time leading receiver at Destrehan High School with a career record of 154 receptions, 2,620 yards, and 30 touchdowns.

[2] Johnson was highly ranked as a college prospect by several websites, but was not shown much interest by the major football schools due in part to his small stature.

In the first quarter, Johnson returned a kick 98 yards for a touchdown to equalize the game at 28 and shift the momentum in favor of Tulsa.

[6] By the game's end, Johnson had accumulated 296 all-purpose yards and was named a Conference USA Player of the Week.

[10] On December 24, 2010, in the Hawaii Bowl game, Johnson broke the NCAA record for all purpose yardage with 326 in a 62–35 win for Tulsa.

[12] Johnson was suspended indefinitely on August 25, 2011, following questions about his role in his girlfriend's arrest for felony embezzlement.

On Friday, September 21, it was announced that Johnson would start along with DeSean Jackson against the Arizona Cardinals, replacing the injured Jeremy Maclin.
