Reuben Foster wasted no time Sunday.

Foster, a rookie linebacker for San Francisco, perfectly read Minnesota’s first play from scrimmage during their preseason game on Sunday Night Football. As soon as Vikings quarterback Sam Bradford released the ball in the direction of running back Dalvin Cook, Foster was already rocketing that way.

Cook never had a chance.

Foster met him as soon as Cook caught the ball, thumping his fellow rookie for a 5-yard loss.

A star during his time at Alabama, Foster was selected with the final pick of the first round in this year’s NFL draft.

Foster collected 115 total tackles (13 for loss) and five sacks in a stellar season for the Crimson Tide in 2016.
