A look at how recent quarterback injuries are affecting NFC West opponents:
Seattle Seahawks: They face a St. Louis team that could be without its top two quarterbacks, Sam Bradford and A.J. Feeley. Tom Brandstater, Kellen Clemens and practice-squad QB Matt Gutierrez are getting the work in practice.
San Francisco 49ers: They face the Pittsburgh Steelers, who could be without Ben Roethlisberger. Roethlisberger said he suffered a high-ankle sprain Thursday night against Cleveland. Players usually need a few weeks to recover from such injuries. However, Roethlisberger could have an easier time playing because the injury affected his left ankle. As a right-handed quarterback, he plants off his right foot.
Arizona Cardinals: They face the Browns, who could be without quarterback Colt McCoy. McCoy suffered a concussion and an injured left hand against the Steelers. His status is uncertain. The Browns sent him home Friday amid questions about whether the team erred in sending McCoy back into the game Thursday night.
Rams: They visit the Steelers. Roethlisberger's status could be a factor.
