Arrington sits out practice; LaBoy, Smith limited

Posted: Updated:

TEMPE -- Cardinals running back J.J. Arrington was sidelined with a knee injury Thursday as Arizona practiced for the first time since winning the NFC championship.

Arrington, who became an increasingly important part of Arizona's offense, was injured in Arizona's 32-25 victory over the Philadelphia Eagles on Sunday.

Coach Ken Whisenhunt was hopeful the extra time off would allow Arrington to be ready to play against Pittsburgh in the Super Bowl on Feb. 1.

"It's hard to rule anybody out for the Super Bowl," Whisenhunt said. "I would hope that he will progress rapidly as the week goes and get some good work in next week. I think the most important thing is that we don't rush it too much this week to make sure that we can push it next week to counterbalance."

Linebacker Travis LaBoy (biceps), defensive end Antonio Smith (knee) and punter Ben Graham (left groin) were limited in practice. LaBoy missed the NFC championship game.

Wide receiver Anquan Boldin went through a full practice and said his left hamstring didn't bother him at all. He sat out Arizona's divisional playoff victory at Carolina with a strained hamstring, but played in the Philadelphia game.

The Cardinals have practices scheduled Friday and Saturday, then take Sunday off before flying to Tampa on Monday.
