Tempers often get heated during NFL training camps.
The joint practice between the Texans and 49ers on Wednesday showed one reason why.
During a one-on-one drill, Texans star wide receiver DeAndre Hopkins and 49ers cornerback Jimmie Ward got into it. Both players threw a few punches and shoves before they were separated and sent to the locker room.
According to reports, the two later shook hands. Ward eventually returned to the practice field.
