Bengals' Iron hobbles off field with injured knee, ankle

Cincinnati Bengals: Bengals rookie running back Kenny Irons injured his left knee and ankle Thursday night against the
Detroit Lions and was taken to the locker room on a cart after
hobbling off the field.

Irons had four carries for 17 yards, including an 11-yard gain,
after replacing starter Rudi Johnson in the exhibition opener for
both teams. The Lions rallied late for the 27-26 win.

The second-round pick from Auburn was hurt when his foot
appeared to get caught up in the artificial turf while making a
stutter-step move. Injuries limited Irons to 893 yards last season
after he ran for a Southeastern Conference-high average of 108
yards per game in 2005.

Cincinnati is already without one of its reserve running backs,
Chris Perry, who is still trying to come back after breaking his
leg last season. Kenny Watson and Quincy Wilson shared the carries
after Irons left the game.

Pittsburgh Steelers: Steelers running back Willie Parker is restless and unhappy at being sidelined for nearly two
weeks because of a sore knee. His teammates are even more eager for
the 1,400-yard rusher to resume practicing.

Coach Mike Tomlin said Parker is so enthused at being involved,
he has become an unofficial player-coach by offering advice
whenever he finds it necessary. Even if most of it is unsolicited

"Willie is a blue-collar worker and all he wants to do is go to
work," Tomlin said Thursday. "The running backs are starting to
call him coach Parker because he's wearing them out. But that's
what makes him what he is."

Parker, who expects to resume practicing Monday, agreed his
mouth moves more quickly than his mind when he watches the other
running backs and sees a mistake. He blames the influence of Jerome
Bettis, the former Steelers star and team leader who was his
unofficial mentor when Parker arrived in Pittsburgh in 2004.
