The Pittsburgh Steelers could be without the services of backup quarterback Byron Leftwich this weekend, just one week after he replaced injured starter Ben Roethlisberger. CBS Sports' Jason La Canfora reports on Twitter that the team is now planning on working out free agent quarterbacks this week to sign in case both Leftwich and Roestlisberger are unable to go on Sunday.

Roethlisberger suffered injures to his shoulder and ribcage in week 9's 16-13 Monday night win over the Kansas City Chiefs. Leftwich started the Steelers' week 10 loss to the Baltimore Ravens, but suffered an eerily similar combination of injuries that could keep him out of action this weekend as well.
