I was beginning to think the whole hamstring thing was rumor unitl I read this. Man you got to feel for the kid. It hasn't been a very good start to his career.

Tough weekend for Pittsburgh first-round draft pick Rashard Mendenhall .

On Friday, during his second practice with the Steelers, Mendenhall tweaked his hamstring badly enough that he was out of action the rest of the weekend.

On Sunday night, Mendenhall flew back to Chicago and returned home to the South Side of the city –- where he was robbed at gunpoint on Monday.

Two men wearking ski masks and hoods pulled a gun on Mendenhall and told him to give them everything he had -– or else. Mendenhall gave the men his wallet, cell phone and car keys. The men returned the car keys, and Mendenhall escaped unscathed.

No arrests have been made
