(Allen Park) The Detroit Lions were punished by the NFL and lost a day of preseason practice after violating on-field contact rules during practice last month.

“We take the rules in place by the NFL for off-seasons very seriously and we have strived to conduct our training accordingly,” the Lions said in a press release Friday evening. We will continue to be vigilant for our future training. »

The Lions conducted a mandatory three-day mini-camp earlier this week.

The Michigan squad had team activities planned Monday, a final session before training camp starting next month, but those had to be abandoned.
