While it’s unclear how long the starters will play tonight in the Lions’ final preseason game against the Bills, expect to see plenty of Aaron Berry, an undrafted rookie cornerback.

The Lions considered Berry a possible starter until he injured a hamstring on Aug. 6 and was held out of practice. He’s healthy and was back at practice this week. This will be his first preseason action.

“He’s had a good offseason and a good camp. The thing that upset me is he got injured because another guy made a mistake. ... But I need to see him play and we all do, he’s done some good things at camp,’’ Lions defensive coordinator Gunther Cunningham said.

Berry, who played at Pittsburgh, went undrafted despite his speed. He ran a 4.3 40 at the Pitt pro day.

If the Lions start Chris Houston and Jonathan Wade at cornerback, Berry could fit in as a backup along with Dre Bly, with Eric King at nickel back.
