ALLEN PARK — Ziggy Ansah, the Detroit Lions’ rookie defensive end, did not practice again today (Wednesday).

Ansah was on the field as the team prepares to play the Minnesota Vikings in the regular season opener on Sunday.

Just like on Tuesday, he did not participate in practice.

The Lions are required by the NFL to file an injury report at 4 p.m. today which will list Ansah’s injury.

It has been speculated that he sustained a concussion on that hit. The team has not confirmed or denied whether Ansah is out due to concussion symptoms.

Ansah took a blind-side hit from teammate Leroy Harris on Aug. 24 during practice.

He has not practiced since then and missed the final preseason game in Buffalo.

Ansah was the only missing player at practice.

Calvin Johnson and Louis Delmas, who missed substantial time during training camp with knee issues, were back at work at least for the early portion of practice open to the media.

The Lions officially reported that running back Montell Owens (knee) has been placed on short-term injured reserve. He will be eligible to return in six weeks. To fill his roster spot they brought back Rocky McIntosh who had been signed during camp.
