49ers coach Kyle Shanahan on recent practice brawls: 'I want people to be irritants,' not fighters - NFL.com

San Francisco 49ers head coach Kyle Shanahan wants his players going right up to the line, but he doesn't want them toeing it.

In response to Niners players exchanging punches -- most notably linebacker Fred Warner and wide receiver Brandon Aiyuk -- at Tuesday's practice, Shanahan let it be known Friday that he wants his players to be tough, to be physical, to even be "irritants," but he doesn't want them throwing hands.

"I want everyone challenging each other," Shanahan said Friday, via team transcript.

"I don't think you have to fight to be intense though.

I think if most people probably voted on who was the most physical team on tape last year, I think we'd win most of that.

And we didn't get in one fight last year, so I don't think that totally pertains to toughness."!

The Panthers were without one of their starting cornerbacks at Saturday's practice, but don't expect to be for long.
