ALLEN PARK — Cornerback Chris Houston, who missed the Lions’ Thanksgiving win over the Packers with a foot injury, was back on the practice field today (Tuesday). 

He participated in the portion of practice open to the media.

Calvin Johnson and Louis Delmas were the only two not participating in the short, bonus practice. Both of them were on the field with their teammates. They routinely miss practice while nursing knee injuries.

The Lions (7-5) play the Eagles (7-5) at Philadelphia on Sunday.

Also, the Lions have signed cornerback Akwasi Owusu-Ansah to the practice squad. He played college ball at Indiana University-Pennsylvania.
