Dallas Cowboys Tanner was signed as an
undrafted free agent by the
Dallas Cowboys after the
2011 NFL draft. On August 21, playing against the
San Diego Chargers at
Cowboys Stadium, he lost his helmet while scoring a
touchdown in the second half of the game. A
new rule canceled the touchdown, because it states that if any player loses his helmet while receiving, running, or intercepting a football, the play will end once the helmet has hit the field. He would end up making the team over
running back Alonzo Coleman. He recorded his first professional carry and touchdown on October 23, against the
St. Louis Rams. On December 9, he was placed on
injured reserve with a
hamstring injury. In
2012, he was the third-string
running back, registering 25 carries for 61 yards, one touchdown and 9
special teams tackles (sixth on the team). In
2013, he was the third-string
running back, registering 9 carries for 12 yards, one touchdown and 9
special teams tackles (fifth on the team). On February 23,
2014, after he was set to count $1.389 million against the salary cap, the Cowboys did not offer a restricted free agent tender, making him a
free agent. During his time with the team, he mainly played on
special teams, while registering 56 carries for 149 yards and 2
touchdowns as a backup
running back.
