ALLEN PARK — It could be interesting at tight end for the Detroit Lions on Sunday.

Rookie Eric Ebron did not practice on Thursday due to a hamstring injury.

With Joe Fauria out with an ankle injury, that left Brandon Pettigrew as the only healthy tight end. Tight end Jordan Thompson is on the practice squad and could be moved up.

Calvin Johnson (ankle) also did not practice which was not a surprise.

Defensive end Ziggy Ansah (toe) who was out on Wednesday, returned to practice today along with wide receiver Jeremy Ross (ankle) who also didn’t practice on Wednesday.

Running back Theo Riddick (hamstring) and linebacker Travis Lewis (quad) was also out.
