Watch: Chargers WR Keenan Allen lands stiff arm of the century on Lions rookie

The NFL may have a new stiff-arm champion. 

Los Angeles Chargers wide receiver Keenan Allen isn't a weak man, but he demonstrated another level of strength in Week 10 against the Detroit Lions. 

Nearing the end of the first half, Allen delivered a stiff arm to Lions rookie linebacker Jack Campbell that would make former running backs like Adrian Peterson and Marshawn Lynch blush.     

After humbling Campbell, Allen caught another pass for a 29-yard gain, helping set up a two-yard touchdown run by RB Austin Ekeler four plays later. 

Allen had already made an impact before landing his stiff arm. On the Chargers previous possession, Allen capped off a 10-play, 75-yard drive, catching a 29-yard touchdown pass from QB Justin Herbert.
