Report: Seahawks RB Rashaad Penny out 3-4 weeks with broken finger.

The dynamic rookie left Monday's practice early after suffering the injury and will undergo surgery Wednesday.

Even in a new season, the injury bug continues to bite the Seattle Seahawks hard in the backfield.

According to Ian Rapoport of NFL Network, Seattle Seahawks running back Rashaad Penny will undergo surgery in Philadelphia to repair a broken finger. He's reportedly expected to miss 3-4 weeks, leaving his status for the season opener uncertain.

Bob Condotta of the Seattle Times originally broke the unexpected news.

Penny, who exited Monday's practice early, becomes the latest in a long line of injury-stricken Seattle running backs. The team lost both Chris Carson and C.J. Prosise to season-ending injuries last season and Prosise has been sidelined by a hip flexor in recent days.

A first-round pick out of San Diego State, Penny rushed for over 2,000 yards and scored 28 total touchdowns for the Aztecs last season. Though his pass protection skills remain a work in progress, he has been in the mix to win the starting gig while competing against Carson in camp.

Penny rushed eight times for 16 yards in his Seahawks debut last Thursday in the preseason opener while also adding two receptions for seven yards.

With Penny expected to miss an extended period of time, the Seahawks will need Prosise, Mike Davis, and J.D. McKissic to help pick up the slack and may need to add a free agent until he returns to action.
