One of the Detroit Lions’ final OTA practices of the offseason has been forfeited after it was determined the team violated collective bargained rules regarding permitted physical contract at a previous OTA.

The team issued a statement on the matter Friday.

“On Friday evening the organization was made aware by the NFL and NFLPA that Organized Team Activities (OTA) practices held the week of May 27 violated player work rules pertaining to on-field physical contact pursuant to the Collective Bargaining Agreement,” the statement read. “As a result, the team’s OTA practice scheduled for Monday, June 10 has been forfeited. We take very seriously the rules set forth within the NFL’s Offseason Program and have worked to conduct our practices accordingly. We will continue to be vigilant with our practices moving forward.”
