(Seattle, WA)  --  The Seahawks are in desperate need of running backs -- plural.  Both Chris Carson and CJ Prosise are out for the season after suffering injuries -- Carson a hip injury and Prosise a broken arm.  Among the names being mentioned by ESPN's Field Yates are Robert Turbin, Alfred Blue, CJ Anderson and Marshawn Lynch.  In other injury news, offensive lineman Duane Brown will have knee surgery today and will, at the very least, miss Sunday's game against San Francisco.
