The Cardinals and Rams are each 1-6 entering Sunday's game, but there are other similarities between the teams.
They both have starting quarterbacks who are limping. Cardinals quarterback Kevin Kolb was wearing a walking boot earlier in the week after suffering a turf toe injury against the Ravens.
Kolb didn't practice Wednesday and appears to be at least questionable for Sunday's game.
Rams quarterback Sam Bradford has missed the past two games with a high ankle sprain. He also didn't practice Wednesday.
If Kolb can't play, John Skelton is expected to start. Skelton started four games last season as a rookie with mixed results. He showed poise under pressure and didn't seem overwhelmed, but he completed just 47.6 percent of his passes.
Skelton lost the backup's job this preseason after suffering a high ankle sprain. With Skelton unable to practice, Rich Bartel moved into the backup's job and kept it through the first five games.
During the bye week, Skelton reclaimed his old position, but he hasn't played this season.
Kolb is hopeful that he will be ready to play, but he admits the toe injury is severe.
"I wish it was called something different than 'turf toe'," Kolb said on his weekly radio segment with XTRA 910-AM. "It sounds like I'm a weenie."
Kolb has not played well this season, but the Cardinals aren't looking to replace him.
Through seven games, his statistics (56.8 percent completion rate, eight touchdowns, eight interceptions) are better than the Cardinals quarterback had through seven games a year ago.
The Cardinals have a lot invested in Kolb, having sent cornerback Dominique Rodgers-Cromartie and a second-round pick in 2012 to the Eagles for him. Then they signed Kolb to a five-year, $63 million deal.
They are willing to let Kolb play through mistakes, because they know he needs the experience, and they hope that it will help his development for 2012.
Toe ailment leaves Kolb's status uncertain
