Terrion Arnold returned to practice on a limited basis Wednesday, Aug. 13, for the first time since injuring his hamstring in late July and the Detroit Lions cornerback said he’ll be a full go at the second of two joint practices against the Miami Dolphins on Thursday.

“I’m practicing tomorrow,” Arnold told the Free Press as he left the field.

Arnold had not practiced since he pulled a hamstring in the Lions’ intrasquad scrimmage July 29.

Lions coach Dan Campbell said before practice Wednesday he was “shooting for next week” for Arnold’s return.

Initially, the Lions hoped Arnold would return last week.

The Lions open the regular season Sept. 7 against the Green Bay Packers.

“He’s getting better,” Campbell said. “He’s doing more every day, but I don’t see him being able to go through these practices.”

Arnold started 15 games and had 10 pass deflections for the Lions last season and is expected to play a key role this season in a secondary that already has suffered injury losses this summer.

Second-year cornerback Ennis Rakestraw will miss the season after undergoing shoulder surgery, backup Khalil Dorsey remains on the physically unable to perform list as he returns from a broken leg and safety Dan Jackson is on injured reserve and out for the year and safeties Kerby Joseph (undisclosed) and Morice Norris (concussion) did not practice Wednesday.

Sione Vaki and Ahmed Hassanein injury update

Campbell said rookie defensive end Ahmed Hassanein will take part in practice after leaving early Monday to be evaluated for a leg injury.

“It was just a little bit of a scare,” Campbell said.

And running back Sione Vaki is expected back for position drills and some team drills after missing most of training camp with a hamstring injury.

“When you can’t practice it’s always a setback, especially when he’s only had very days to where he was in,” Campbell said.

“But it is what it is and that’s behind you and you got to call this Day 1, what are you going to do about it? So it’s just good to get him back on the grass.”
