Where Roethlisberger would be missed

PITTSBURGH -- Steelers coach Mike Tomlin will give updates on quarterback Ben Roethlisberger's shoulder injury at his noon news conference. Here are the areas where Roethlisberger will be missed the most if he is sidelined by the injury:

Third downs: His 47 percent conversion rate on third-down throws this season is second best in the NFL, trailing only Falcons quarterback Matt Ryan, according to ESPN Stats & Information.

Red zone: Before Monday night's game, Roethlisberger had the fifth-best QBR (92.3 out of 100) inside the opponents' 20-yard line. His 7-yard fade pass to Mike Wallace in the second quarter was his 13th red zone touchdown toss of the season. He hasn't been intercepted in the red zone this season.

Outside the pocket: Roethlisberger often does his best work when he is scrambling around and extending plays. Before Monday night's game, he had the seventh-best QBR (85.9) on passes outside the pocket. He had completed 63.6 percent of his passes and averaged 7.7 yards per completion.

Short passing game: He had adapted to Todd Haley's offense, which stresses shorter, quicker and safer passes. Prior to Monday night's game, his QBR on passes 10 yards or less ranked fourth (79.6) in the league. He threw 14 touchdowns and one interception on such passes.

When defenses don't blitz: Roethlisberger has been one of the best when opponents have rushed four or fewer pass-rushers. His 69 percent completion rate and 11 to 3 touchdown-to-interception ratio both rank in fourth best in the NFL (tied for fourth in ratio), according to ESPN Stats & Information.
