Running back J.J. Arrington, who missed all of last week's practices with a sore right knee, went through a limited workout for the second day in a row. He took part in offensive drills but sat out special teams work at the end of practice.
"We were worried about him slipping and doing something to his knee," Whisenhunt said.
Arrington is the team's primary kickoff returner.
Whisenhunt said he was pleased that the rain didn't disrupt practice.
"Who knows?" he said. "It's not supposed to be like this on game day, but if it does rain at least we got a lot of work in with wet balls and operating on a field that is a little bit wet."
"It helps our receivers and Kurt (Warner) in order to identify defenses," Whisenhunt said. "Where a certain defensive player shows up, you may have plays predicated off of that. Now, this is something we do all year on a weekly basis. I saw one thing this year before Tennessee played Pittsburgh, they had a player running around on the field with a big long wig hanging out of his helmet to impersonate Troy."
