49ers coach Kyle Shanahan explains viral sideline exchange with Brock Purdy, who yelled at him during game

The San Francisco 49ers are red-hot to start the 2026 season, owning a perfect 6-0 record after a "Monday Night Football" victory over the Washington Commanders.

But tensions can run high even when things are going well. Just ask head coach Kyle Shanahan and quarterback Brock Purdy after the latter screamed toward his leader on the sideline in a now-viral exchange in Week 6.

Purdy was heard shouting, "Hey, Kyle!" with clear frustration, and the clip quickly found its way around social media. It appeared that Purdy wasnt happy that Shanahan didnt have the play-call in his ear in time.

Ahead of the 49ers matchup with the this week, Shanahan told a different story on the exchange.

"Yeah, its actually not to call a play faster," Shanahan replied when asked about it by a reporter. "Its, I need it again, and it gets cutoff at 15 [seconds]."

Communications within a quarterbacks helmet can sometimes cause issues with getting play calls in on the sideline in time. That seemed to be the case here.

"Sometimes no one can hear it," Shanahan added. "… I always call a play and I just walk, and think. I dont always watch the huddle. A lot of times. Mac [Jones] or someone will say, We didnt get it, it was chopped or somebody yells, Brocks yelling at you, which I cant always hear. But I did hear him a couple times in this game, and I look up and try to do it again as long as its not past 15 seconds."

Shanahan is known as one of the best offensive play-callers in the sport, but its not always smooth sailing on game day. The clock is always playing a major factor, but the chemistry between play-caller and quarterback is what matters most.

So, theres no disconnect on that front, as Shanahan has seen Purdy be one of the top signal callers in the game thus far through this undefeated start.

For quarterbacks who have played through all six weeks, Purdy owns the leagues best quarterback rating (118.1) while throwing for 1,460 yards with a 69.6% completion rate, 14 touchdowns and only two interceptions.

Shanahan, Purdy and the rest of the 49ers will aim to remain unbeaten in Week 7 down in Atlanta.
