He played college football for the Georgia Tech Yellow Jackets and was selected by the Pittsburgh Steelers in the sixth round of the 2010 NFL draft.

[2] After committing to Georgia Tech, Dwyer got plenty of playing time as the backup running back to senior Tashard Choice.

Choice battled leg injuries during the course of the 2007 season, which led to Dwyer rushing for 436 yards on 82 attempts and nine touchdowns.

The following week, in a disappointing loss to the North Carolina Tar Heels, Dwyer recorded 157 yards on the ground, 85 of them coming in a long touchdown run where he again displayed his speed.

Dwyer's stock began to fall as questions about his weight and conditioning arose, including notably after the NFL combine (40 yard dash: 4.59, 3-Cone Drill: 7.56, 20-yard shuttle: 4.67, Bench: 15 reps).

He had a strong performance, rushing for 107 yards on 11 carries, including a 76-yard dash to set up a short Ben Roethlisberger touchdown pass.

On November 27, 2012, Steelers head coach Mike Tomlin announced that Dwyer had earned the starting job for the remainder of the season.

[9] However, on September 9, 2013, the Steelers re-signed him due to LaRod Stephens-Howling suffering a torn ACL during their season opening game against the Tennessee Titans.

[11] On September 17, Dwyer was arrested for domestic violence, and as a result the Cardinals deactivated him from all team activities, placing him on the non-football injury list.

On September 29, 2014, aggravated assault charge, a class 4 felony, was returned by a Maricopa County Grand Jury.

Dwyer also was indicted on eight misdemeanors that included one assault charge for the incidents concerning attacks against his wife and 18-month-old child on July 21 and 22 that occurred at their home.

[14] Jan 30, 2015, Dwyer pleaded guilty to charges of disorderly conduct, a misdemeanor, in Maricopa County Superior Court Thursday.

He was taken into custody after a practice with the Cardinals in September, and right after the video footage of ex-Ravens running back Ray Rice hitting his then-fiancé went public.
