"We're still all right," Petrino said. "We're just getting thin. We can't afford to have another injury there."
Crawford became the third receiver sidelined with an injury when he went down in the second half of Saturday's 48-10 win against Missouri State. Senior Lucas Miller also is out with a broken collarbone and junior Marques Wade has been slowed by a sore knee. Tight end Chris Gragg also is done for the year after suffering a broken ankle earlier this summer.
The injuries leave Jarius Wright, Joe Adams, Greg Childs, Cobi Hamilton, Carlton Salters and Reggie Fish as the players who will receive the bulk of the work in preparation for Arkansas' game against Georgia on Sept. 19. Petrino said Wade did practice more than usual Tuesday and Miller worked out for the first time since his injury, running routes and catching passes with a trainer. But neither is ready to play — yet.
The absences mean Arkansas' receivers must shoulder more reps in practice this week. Wright said it makes things "a little tougher," but they'll get by.
"We're receivers," Wright said. "That's what we do. We run. So we should be used to it by now."
• Apparently, Arkansas' receivers and running backs hold a weekly contest. Coaches keep track of yards after catch for receivers and yards after contact for running backs. The winner gets bragging rights.
Petrino said the receivers won Saturday with roughly 150 yards. Running backs finished with less than 100.
"We need to get after the running backs for them to get more yards after contact," Petrino said.
• Starting cornerback Ramon Broadway was not on the field during the portion of practice open to the media Tuesday. Broadway, who started the opener and had three tackles, was replaced by Andru Stewart with the first team during the first 20 minutes.
• Injury report: OG Grant Cook and DE Damario Ambrose did not attend practice. Petrino confirmed their absence after the workout, but declined to comment on the two linemen.
In addition, S Elton Ford, who was sidelined for the opener with an ankle injury, practiced. WR Lance Ray, who is scheduled to redshirt, did not practice and worked off to the side with an unknown injury.
• It may be just one week, but the Razorbacks' passing offense is No. 1 in the nation. Arkansas is tied with Houston for the top spot in the country in passing yards per game after its 447-yard effort on Saturday.
INSIDE SCOOP: Petrus Back In Action
All eyes were on Arkansas quarterback Ryan Mallett as he returned to the field Saturday in Little Rock. But the Michigan transfer wasn't the Razorbacks' only offensive player returning from a one-year layoff.
Starting guard Mitch Petrus also made his return — albeit, a low-key one compared to Mallett — in Arkansas' win. Petrus, who missed the 2008 season for academic reasons, said he was ready to play.
"It felt good," Petrus said. "I had to shake a little rust off. I was so focused on doing everything perfectly I didn't have a lot of time to soak up the atmosphere like I wanted to. But as the game went on, I became a lot more comfortable with what was happening."
Petrus was part of an offensive line that didn't allow a sack, showing improvement from 2008.
He got more reps than the rest of the starters. Petrus was the only one to stay in the game when the second-team group was on the field Saturday night.
Petrus didn't mind any of the work, though, after having to sit on the sideline for an entire season.
"You don't get the opportunity your whole life to run through the ‘A' and play in front of that many people," Petrus said. "So I was truly thankful."
