ALLEN PARK, Mich. (AP) -- Detroit rookie Ziggy Ansah was able to practice Thursday, a sign that his recovery from a concussion may be progressing.
Ansah, a defensive end, took part in drills during the portion of practice that was open to reporters. The previous day, he did some running off to the side during practice, and later Wednesday, the team finally acknowledged that he was recovering from a concussion. Ansah did not travel to Detroit's preseason finale at Buffalo last week.
Ansah was the No. 5 pick in this year's draft. He was believed to have hurt his head after colliding with a teammate in practice Aug. 24.
The Lions open the season against Minnesota on Sunday.
