Practice notes: TE Dray's expanded role

Arizona Cardinals quarterback Carson Palmer said he was pleased with backup tight end Jim Dray, who caught two passes for 21 yards Sunday in St. Louis with starter Rob Housler sidelined by an ankle injury.

“He made a couple of really tough catches, made a really nice run and broke a couple of tackles,” Palmer said.

According to Pro Football Talk, the Cardinals tried out tight ends Brett Brackett and Ryan Otten and receiver Raymond Radway on Tuesday. Since no announcement has been made yet, it’s unlikely the Cards signed any of them.

Palmer hinted that Dray's role in the offense may grow Sunday against Detroit.

“I think Jimmy has done a great job with his backup role,” Palmer said. “I think this week he is even going to expand on that a little bit.”

Depth chart changes: On the Cardinals’ latest depth chart, Nate Potter was listed as a backup for left guard Daryn Colledge, while recently acquired Bradley Sowell will back up Levi Brown at left tackle.

“We’re trying to get him some guard work now,” Cardinals coach Bruce Arians said. “Bradley Sowell, we’re comfortable with playing both tackles.”

Arians said Sowell will not play at left tackle Sunday.

Suh’s reputation not a problem for Arians: Arians knows what he sees when it comes to Ndamukong Suh, who was fined $100,000 for an illegal low block against he Vikings.

“The only thing I evaluate is tape, and when I watch tape, I see a great football player -- high energy, high passion, disruptive three-technique,” Arians said. “All the rest of the stuff, I don’t have to deal with.”

Never too old: Palmer identified areas he struggled in at St. Louis and said he set out to improve them this week.

Palmer said he had technique issues stepping into throws, reading the coverage and getting himself out of trouble in the pocket. He watched relevant tape Monday and Tuesday, then came to work Wednesday with a few footwork drills he could do with quarterbacks coach Freddie Kitchens.

Minter to keep waiting: It’s not likely that rookie linebacker Kevin Minter will see the field behind Jasper Brinkley and Karlos Dansby on Sunday, or any game in the future.

“Only in the case of injury,” Arians said.

Minter participated in 17 special-teams plays against the Rams.
