Troy Aikman Shows Off Arm In Viral ‘Eight Can Challenge’ Video

Watch out, Dak Prescott and Cooper Rush … Troy Aikman showed he’s still got magic left in his right arm — knockin’ down 12 beer cans with two, pinpoint 20-yard throws!!

The Dallas Cowboys legend hit a field in Texas to complete the feat — and while he tells TMZ Sports the footage might not be “100 percent” real … he did say the accuracy he showcased in the vid is legit!!

“That was my strength, you know?” the 55-year-old said with a laugh.

Troy performed the stunt in hopes of igniting a viral craze — where people think of creative ways to knock down pyramids of EIGHT Beer cans — that will benefit a great cause.

Aikman dubbed it the “#EIGHTBeerChallenge” — and he said for every one person who participates in it, films it, and shares it to social media, he and his beer co. will donate $8 to Back On My Feet, an org. created to combat homelessness.

“It gives a chance for some of the homeless people in the community to be empowered,” Aikman said, “and to get them back on their feet, being an active participant in society, doing a lot of different things.”

Aikman said he’s planning on showcasing some of the best vids of the challenge on his social media pages over the coming weeks.
