49ers-Browns kicked off a little earlier than Sunday’s scheduled 10 a.m. start time.

Before the game, both teams ended up along the same sideline. It’s unclear how that started, but you can see Brandon Aiyuk and Deebo Samuel jumping in front of some Browns players. A Browns player shoves Aiyuk, Samuel shoves him back, and then…

And then Trent Williams got involved.

It’s all fun and games when it’s receivers and defensive backs. When Williams gets in the mix — knocking the helmet off Browns receiver Elijah Moore — it’s not fun anymore.

Here’s a closer look at Williams coming in hot.

Charlie Woerner seems thoroughly confused.

Williams, though, knows exactly what’s going on. You can see in the extended video above that even as both teams are separated, there are still some lingering Browns players talking at 49ers players. Williams basically tracks every one of them down and ends things.

Again, no one really wants to fight Trent Williams.
