A screenshot from a video (via Twitter) showing Motekiai Langi tackling a running back. 

He's 6-foot-7 and 410 pounds, and he's looking for a running back to devour. 

BYU — LSU's opponent in its season opener — recently posted a video of the class of 2015 commitment Motekiai Langi during practice, and he's as big as advertised. 

In the video, the Cougars' nose tackle comes out of a three-point stance and easily takes down the running back in the drill with one arm.

The native of Tonga had never taken a snap of football before he was offered a scholarship two years ago, according to a report from Yahoo! Sports. Langi is a relative of current NFL player Harvey Langi. 

It's unclear how much, if at all, Langi is expected to play in the opener. 

BYU and LSU will face off in Baton Rouge on Sept. 2 at 6:30 p.m. (ESPN).
