Quarterback Kevin Kolb, out with a concussion, stands next to offensive coordinator Mike Miller during last weekend's game against the 49ers.

With a concussion, Kevin Kolb doesn't want to be irresponsible.

"It's a touchy subject," the quarterback said Wednesday, after taking part in a "little bit" of practice with the team. "We want to make sure we err on the right side."

Nothing was definitive with Kolb in terms of his availability for Sunday's game with Cleveland. Both he and coach Ken Whisenhunt said he will continue to do more at practice daily.

"I want to be out there as much as anybody," Kolb said, "but this is something you don't push."

That couldn't be more clear than this week, with the coincidental matchup against the Browns – who have spent the last few days explaining how their own quarterback, Colt McCoy, suffered a concussion last week against Pittsburgh yet went back in and played the rest of the game.

Kolb at least was able to return to do some work. McCoy was still sidelined Wednesday, almost a week since the Browns last played. The Browns acknowledged McCoy was not examined for a concussion during the game.

"Obviously hindsight is 20-20," Browns coach Pat Shurmur said. "As coaches on the field, you see a lot of collisions during the game and we don't have the benefit of replay or HDTV. We've all seen injuries where a guy runs down the field, falls down and he's lost for the year. We've seen pileups that look like car crashes and the guy pops right up.

"(The medical staff) said to me, 'Hey, he's ready to play.' Aside from the interception before the half, you could say he was battling through a gritty AFC North game. Had I known he was hurt, I would obviously have never put him in the game. But the symptoms didn't show up until later."

Whisenhunt said the Cardinals have always emphasized to their players to be honest how they feel when it comes to concussions. Former Cardinals Pro Bowl special teamer Sean Morey – who retired in part because of concussion concerns – became an activist on the subject at the end of his time in Arizona. Former quarterback Kurt Warner sat out a game in 2009 to make sure he had fully recovered from a concussion suffered the previous week.

Kolb not only has been working with the Cardinals' doctors but also a neurologist at St. Joseph's hospital. Asked about worrying about the long-term effects of concussions, Kolb said "to say it doesn't cross my mind would be crazy."

"But," Kolb added, "you still have to go play the game the same way and I will once I'm back out there. That's not an issue at all."

RHODES RETURNS FULL

For the first time since breaking his foot Oct. 9 in Minnesota, safety Kerry Rhodes practiced full Wednesday and is in position to be available to play for the first time in more than two months against Cleveland. He is expected to be available this week barring any setbacks.

Safety Sean Considine, who was nursing an Achilles injury last week and then was forced to sit out Sunday's game after hurting himself in pregame warmups, was the only Card to sit out practice.

Seven Cardinals aside from Kolb were limited: linebacker Clark Haggans (hamstring), tight end Rob Housler (shoulder), tackle Brandon Keith (knee), linebacker Joey Porter (knee), wide receiver DeMarco Sampson (ribs), punter Dave Zastudil (biceps) and running back Beanie Wells (knee).

For the Browns, not only was McCoy sitting out, but so was key playmaker Josh Cribbs (groin) and tight end Ben Watson (head). The Browns have been off for almost a week already, having played last Thursday.

PRO BOWL VOTING

The only Cardinal that has shown up in the top five of Pro Bowl voting at any position is wide receiver Larry Fitzgerald, who is fourth among NFC wideouts (behind Detroit's Calvin Johnson, Green Bay's Greg Jennings and Carolina's Steve Smith). Voting ends early next week, and then players and coaches will vote.

Rosters are announced the final week of the regular season.

"There are always going to be some guys that get into the Pro Bowl because they have had a good statistical year or because of their reputations," Whisenhunt said. "You understand that, but I don't think you can judge a player's year (on the Pro Bowl). There have been a lot of guys that haven't made the Pro Bowl that have had very good years."

RHODES AND CHARITY

Injury or not, Rhodes is hosting his third annual holiday shopping "extravaganza" and celebrity billiards tournament Dec. 19, which is open to the public. During the day, various stores at Scottsdale Fashion Square Mall will extend a percentage of all purchases to the Kerry Rhodes Foundation. Then, from 7 p.m. to 1 a.m. at the Cactus Moon Sports Grill in Mesa, Rhodes and his teammates will take part in the pool tournament with fans.
