SANTA CLARA, Calif. – The San Francisco 49er’s head coach Kyle Shanahan halted practice last Tuesday after the teammates were caught throwing punches not once but twice at one another.

Shanahan said he wants this team to be tough, but he draws the line at punching.

The disputes were noted by ESPN to mostly be between star middle linebacker Fred Warner and receiver Brandon Aiyuk.

Shanahan noted this behavior will not be tolerated and it comes at the cost of the entire team.
