GREEN BAY, Wis. (AP) — The Green Bay Packers have placed rookie linebacker Kamal Martin and cornerback Kabion Ento on injured reserve and have signed cornerback Parry Nickerson.

Martin and Ento will be eligible to return after missing at least three games.

The Packers didn’t specify the injuries for Martin and Ento, though ESPN has reported that Martin has a torn meniscus in his left knee.

Martin, a fifth-round draft pick from Minnesota, had been competing for a potential starting spot at inside linebacker. Martin’s injury means that the native of Burnsville, Minnesota, won’t get to make his NFL debut in his home state when the Packers face the Vikings on Sunday.

Ento, a 2019 undrafted free agent from Colorado, spent all of last season on the Packers’ practice squad.

Nickerson played four games and made one start with Jacksonville last year and spent the rest of the season on the Jaguars’ and Seattle Seahawks’ practice squads. He played 16 games and made two starts in 2018 for the New York Jets, who drafted him in the sixth round from Tulane earlier that year.

Lions announce

Peterson signing

ALLEN PARK, Mich. (AP) — The Detroit Lions announced the signing of Adrian Peterson Monday.

The 35-year-old running back comes to Detroit after being released by Washington. He has rushed for 14,216 yards in 13 seasons, mostly with the Minnesota Vikings.

Peterson is 1,053 yards behind Lions great Barry Sanders for fourth on the career rushing list. He rushed for 1,940 yards and 12 touchdowns over two seasons with Washington.

Peterson’s 898 yards in 2019 would have led the Lions in rushing in any of the past six seasons.

Detroit opens the season this weekend at home against Chicago.
