The New York Giants and Detroit Lions were disciplined by the NFL on Wednesday following two days of fights at their joint practices.
There were at least four fights involving multiple players from both teams on Monday. On Tuesday, Giants rookie receiver Malik Nabers and Lions safety Kerby Joseph were involved in an altercation.

The teams were fined $200,000 each.
“All NFL clubs were reminded in a memo sent last month that fighting and unprofessional conduct at team practices would not be tolerated,” the NFL said Wednesday.
Two of Monday's fights involved Lions star Amon-Ra St. Brown, safety Dane Belton and rookie cornerback Dru Phillips. Giants quarterback Daniel Jones was involved in an incident with center Greg Van Roten on the field, in which a Lions player jumped on him.

Lions defenseman Emmanuel Moseley was injured in one of those fights and is out indefinitely.
“Practice is a little different than a game,” Giants head coach Brian Daboll said Tuesday via the team's website. “Obviously, you can't do that in a game. We're going to try to correct some of the things that led to that, but we're going to play hard and be physical and have another good practice.”
Lions head coach Dan Campbell said the fights just “waste everyone's time.”
