Saints running back Travis Etienne returned to practice on Wednesday as a limited participant.

A hamstring injury in Week 3 sent him to injured reserve.

The Saints have 21 days to activate him back to the active roster, but he could return as soon as Sunday.

“We’ll see,” head coach Kellen Moore said Wednesday, via Mike Triplett of NewOrleans.Football. “There’s some potential for it. But . . . we’ll just let the week kind of play out and see what it looks like.”

Etienne has 28 yards rushing, 51 yards receiving and no touchdowns.

Center Erik McCoy (biceps), running back Alvin Kamara (rest/back) and running back C.J. Donaldson (shoulder) did not practice.

Moore said Cesar Ruiz will start at center in McCoy’s absence with Jeremiah Wright taking Ruiz’s spot at right guard.

Offensive tackle Kevin Banks (ankle), offensive guard David Edwards (knee), cornerback Martin Emerson (shin), tight end Noah Fant (back) and defensive tackle Christian Miller (knee) were limited.
