Brooks, who was hurt after fumbling the snap from center on two consecutive plays, underwent an MRI test earlier in the day and that revealed a strained pectoral muscle. While there was no damage to the rotator cuff -- as team officials had originally feared -- it was significant enough to send the veteran quarterback to the sidelines for the next few weeks.
In his place this past Sunday, Walter completed 10-of-27 for 162 yards. He was intercepted three times, sacked six times and fumbled three times, losing one.
Maddox appeared in three games for the Steelers last season in place of an injured Ben Roethlisberger and completed 34-of-71, a 47.9 completion percentage, for 406 yards with two touchdowns and four interceptions.
He won NFL Comeback Player of the Year Award for his performance during the 2002-2003 season when he passed for 2,836 yards on 234-for-377 passing with 20 touchdowns and 16 interceptions.
Tommy Maddox is the only football player to hold both a Super Bowl ring, and XFL championship ring. However, Maddox was the only Steelers player not to attend the ceremony at the White House honoring their Super Bowl championship.
While the Raiders spent time looking at Maddox, they also worked out a defensive back.
Michael Hawkins, a cornerback/safety who spent the 2005 season with the Green Bay Packers, was brought in for a tryout.
The former Oklahoma Sooner and AFL star, was taken by the Packers in the fifth round of the 2005 NFL Draft and saw action in 11 games for the Packers last season, registering 13 tackles and two passes defensed.
He missed five games to injury in 2005 and suffered a slight tear of the meniscus in his knee during a Packers minicamp in June. He was subsequently placed on injured reserve by the Packers but is reportedly healthy and can sign with any team except Green Bay.
Hawkins saw action in five games for the University of Oklahoma Sooners as a true freshman. He recorded five tackles, a pass defensed and an interception, which he returned 45 yards for a touchdown. He was kicked off the team for disciplinary reasons midway through the season.
