C.Trent: DeDe Dorsey carted off field

C. Trent, at minicamp, writes that DeDe Dorsey was carted off the field. No word on the extent of the injury; or if it's just a cramp (though that's rarely an issue that requires the cart). This, again, puts a wrench at running back. Kenny Irons arrived at camp, but not running drills with the running backs. DeDe Dorsey was projected as the third or fourth back, depending on Chris Perry's health -- which Chick Ludwig says isn't 100%.

If Dorsey's injury turns out serious, if Perry isn't 100% and likely Irons not playing this season, makes you wonder: Do the Bengals sign Shaun Alexander?

UPDATE: Mark Curnutte confirmed . Injury still unknown.
