The Detroit Lions will be in search of a new position coach this offseason after parting ways with inside linebacker coach Mark DeLeone this week. The circumstances of the departure remain unclear. Both he and multiple team sources declined comment.
Son of legendary offensive line coach George DeLeone, Mark joined Detroit's staff last offseason after two years with the Chicago Bears. He's also spent time with the New York Jets (2012) and Kansas City Chiefs (2013-18).
In 2021, DeLeone started the year with a veteran group, led by Jamie Collins and free-agent addition Alex Anzalone. That dynamic shifted quickly when Collins was cut early in the season after the team decided to go in a different direction and couldn't find a trade partner.
