The Detroit Lions report that rookie defensive end Ziggy Ansah participated Friday in a full practice as the team prepares for Sunday's season opener against the Minnesota Vikings at Ford Field.
Ansah, the No. 5 pick in this year's draft, has been recovering from a concussion.
He did not travel for the team's preseason finale at Buffalo last week. He was believed to have hurt his head after colliding with a teammate in practice Aug. 24.
The team says Ansah, safety Louis Delmas and defensive end Jason Jones are probable for Sunday's game.
Head Coach Jim Schwartz also says receiver Calvin Johnson, quarterback Matthew Stafford, defensive tackle Ndamukong Suh, linebacker Stephen Tulloch, kicker David Akers and safety John Wendling were voted in as team captains.
