Cardinals hope for the best with injured Wilson set for MRI

The Arizona Cardinals are holding their breath following an injury to safety Adrian Wilson during the team's practice session on Saturday.

Wilson injured either his bicep or elbow early in practice, according to a report on the Cardinals' team website.

Wilson will undergo an MRI exam to determine the extent of the injury. Perhaps bracing for bad news, *The Arizona Republic* reported the Cardinals will re-sign safety Matt Ware, pending a physical.

Rookie cornerback Patrick Peterson referenced Wilson's situation on his Twitter account Saturday.

"What a great practice today, but I will need everyone on twitter to keep my big bro @adrian_wilson24 in their prayers THANKS," he wrote.

Losing Wilson for any length of time would be a huge loss for the Cardinals on defense. The 31-year-old is a four-time Pro Bowler who was recently ranked 89th on NFL Network's "Top 100: Players of 2011" countdown.

Wilson is coming off a difficult season in which he dealt with a nagging abdominal issue, but he still managed to record 88 tackles, 2.0 sacks, nine passes defended and two interceptions. The Cardinals are already facing challenges in their secondary after the team traded cornerback Dominique Rodgers-Cromartie to the Philadelphia Eagles last month. Peterson, the No. 5 overall pick in April's draft, is expected to step into a key role.
