Green Bay Packers cornerback Demetri Goodson practiced for the first time this season on Wednesday, starting the clock on a roster decision with only three options.

The Packers now have three weeks to activate Goodson from the PUP list, send him to injured reserve or release him.

A sixth-round pick in 2014, Goodson suffered a season-ending knee injury during a November loss to the Washington Redskins last season. Goodson missed the entire offseason and started the regular season on the PUP list.

He’s roughly a year removed from surgery.

Goodson will now have 21 days to prove to the Packers he’s healthy and capable enough to win a spot on the 53-man roster.

The Packers currently have six cornerbacks on the roster, including three rookies. Goodson may have to win a job back from rookie cornerback Donatello Brown, who was promoted from the practice squad two weeks ago.

Experience should give him a chance. Goodson played 182 snaps on defense and another 63 on special teams for the Packers last season.

Over 26 career games, Goodson has 30 tackles and two passes defended. He made three starts at cornerback in 2016.

Rookie linebacker Vince Biegel, who joined Goodson on the PUP list to start the year, earned activation to the 53-man roster on Nov. 3.
