The San Francisco 49ers defense set the tone early against Dak Prescott and the Dallas Cowboys on Sunday Night Football. After drilling a field goal to take a 3-0 advantage, Ji'Ayir Brown came up with a timely play to get the ball back to Brock Purdy and the 49ers' offense.

With just under five minutes remaining in the first quarter, Prescott fired a deep shot toward Kevonte Turpin that landed in the open arms of 49ers safety Ji'Ayir Brown.

Via @49ers on Twitter:

Prior to the interception, Nick Bosa was able to apply some pressure in the face of Prescott. With Bosa looming,  Prescott wasn't able to get much power into the pass downfield. After Prescott got rid of the football, Bosa blasted the Cowboys' passer.
