METAIRIE, La. New Orleans Saints running back Darren Sproles worked for the past two days after sitting out the five practices as well as the preseason game against Jacksonville this past weekend.
But acting head coach Joe Vitt said it's likely Sproles won't play for the rest of the preseason.
And offensive coordinator Pete Carmichael Jr. isn't worried that Sproles is missing game time.
'We feel comfortable with that,' Carmichael said. 'That's fine. The important thing is for him to get ready for that Week 1 game.'
Meanwhile, the Saints lost another linebacker this week when Ramon Humber pulled a hamstring on Tuesday. Humber's hamstring injury is considered a Grade I pull, Vitt said, and he's expected back in about 10 days.
Eight other players sat out Wednesday's session.
Receiver Nick Toon (foot) and cornerback Kamaal McIlwain (groin) were doing rehabilitation running during practice.
Additionally, cornerback Jabari Greer (sports hernia) and receiver Adrian Arrington were at practice, though they continued to watch from the side.
Linebackers Curtis Lofton (ankle) and David Hawthorne (knee), receiver Andy Tanner (ankle), defensive tackle Tom Johnson (ankle) and cornerback Marquis Johnson (knee) weren't at practice.
Lofton would play this week if it had been a regular season game, Vitt said.
Without Humber, the Saints are now down the top four middle linebackers, including Jonathan Vilma. Lofton is out at least this week while reserve linebacker Chris Chamberlain was lost for the season with a torn left anterior cruciate ligament.
In related news, Vitt said newly-acquired linebacker Barrett Ruud likely won't play this weekend against Houston.
