METAIRIE, La. -- The competition for the New Orleans Saints' third running back spot could become more intense in the next few days.
Saints coach Sean Payton said Sunday that the team was pursuing a replacement for Lynell Hamilton, who suffered a torn anterior cruciate ligament in his right knee Wednesday during a joint practice with the New England Patriots.
"We're looking right now, so I wouldn't say we're staying pat," Payton said. "We just haven't signed anyone in the last two days. Hopefully we're able to get someone in here that we have a high enough grade on."
New Orleans has lost almost half of its running back carries from last season.
The other two running backs on New Orleans' roster are P.J. Hill, a second-year pro who was on the practice squad for part of 2009, and Chris Ivory, an undrafted rookie.
"Right now, to be fair to those two players, they have a lot of work ahead of them," Payton said. "Both of them have shown some real positive signs, but there's still a number of things that they're working on to get fully up to speed. I'd anticipate that we'll be able to get someone in here before the Texans' (preseason) game (next Saturday)."
Hill's and Ivory's lack of pedigree isn't the issue. Thomas, who has led the Saints in rushing the past two years, wasn't drafted out of Illinois in 2007. Bell and Hamilton were undrafted free agents, too.
Hill's and Ivory's lack of experience is the concern.
Hill, a three-time 1,000-yard rusher at Wisconsin, spent time on the practice squads of the Saints, Eagles and Washington Redskins as a rookie last year without being activated. He had nine carries for 30 yards against the Patriots on Thursday in the Saints' preseason opener. He also fumbled near New England's goal line as he tried to fight for extra yards late in the fourth quarter.
Although Hill insisted his knee was down before the ball came loose, the play didn't help his job security, particularly since he already had fumbled a couple of times during training camp. He bobbled a pitch in Sunday's practice.
"I can't make errors like that," Hill said. "I've got to be able to hold on to the ball. That's one of our first rules is protect the ball. I'll take that blame even if (the fumble against New England) came out late."
Ivory, who has earned Payton's praise more than once during training camp, faced long odds when he signed with the Saints. He rushed for 534 yards in three injury-filled seasons with Washington State, then transferred to Division II Tiffin University in his senior year. He gained 227 yards in five games with Tiffin, which went 0-11, before a leg injury sidelined him again.
"He carries his pads well," Payton said. "He has good speed, and he's big and put well together."
Ivory carried six times for 30 yards with a 2-yard score against New England.
"I feel like I have the opportunity to play," he said. "That's why I came here. If (Thomas) came in as a free agent, I know I can do it, too. I think I have a good shot."
Notes: Backup FS Usama Young sat out Sunday's practice with a groin injury. Payton said it was unclear when Young would return or whether the injury was related to the sports hernia surgery he had in December. ... The best play of Sunday's practice came on a 35-yard pass from Drew Brees to TE Jeremy Shockey near the goal line. But backup S Chris Reis, who was beaten despite having tight coverage, insisted Shockey didn't get his feet inbounds. ... Rookie CB Patrick Robinson, a first-round draft pick, had two interceptions, one day after defensive coordinator Gregg Williams criticized him. "Patrick has a lot of skill, but right now, he doesn't know how to play," Williams said. "Right now, I don't have any trust in him. He has to take the next step up in pro football. He's had too much down time, and he doesn't know how to take care of his body."
