Warm-up: Looking at quarterbacks

Here's your game-day warm-up:

SAN DIEGO -- I'll be covering the Ravens at Chargers game tonight, but I will have wrap-ups for the afternoon games involving the Bengals and Browns. The Steelers play at the 49ers on Monday night.

Here's a look at the quarterback storylines for the division:

BENGALS: Andy Dalton, who plays at St. Louis today, has enjoyed more success than most rookie quarterbacks on the road, throwing 12 touchdowns and six interceptions for an 85.1 passer rating. He needs 139 passing yards to surpass Joe Flacco for the fifth-most by a rookie quarterback in NFL history.

BROWNS: Seneca Wallace replaces an injured Colt McCoy (concussion) today at Arizona and takes over an offense that ranks 30th in scoring (13.7 points per game). Wallace, 31, makes his first start since October 2010. "To see another quarterback execute and operate with the players on the field may help us learn something about everybody involved," coach Pat Shurmur said, via The Cleveland Plain Dealer.

RAVENS: Joe Flacco, who plays tonight at San Diego, is tied with Green Bay's Aaron Rodgers for the most road wins since 2008 with 20. In those victories, Flacco has thrown 23 touchdowns and five interceptions for a 93.8 passer rating.

STEELERS: Ben Roethlisberger (ankle) is questionable at San Francisco after limited participation in Friday and Saturday practices. Charlie Batch would replace Roethlisberger, according to offensive coordinator Bruce Arians. Roethlisberger hasn't missed a game due to injury since November 2009.
