The Steelers won an ugly 16-13 game against the Kansas City Chiefs, in large part to timely penalties and mistakes committed by Kansas City. But the bigger happening was an injury to Ben Roethlisberger's right shoulder. Roethlisberger exited the game in the 3rd quarter after being sandwiched between two Chiefs blitzers and driven to the ground. His status for next week's game against Baltimore likely won't be known until later this week, but it looks murky at best. Lawrence Timmons intercepted Matt Cassel on the second play of overtime and returned it to the 3-yard line to set up Shaun Suisham for the game winning 23-yard chip shot. Kansas City rallied to tie the game in regulation on a 46-yard field goal by Ryan Succop as time expired. Cassel connected with TE Tony Moeaki on a 4th down to put Succop in position for the tying kick. Timmons' interception was the big splash play the Steelers needed after a lifeless, if effective, performance. Byron Leftwich came in for Roetlhisberger and led the Steelers to a go-ahead field goal early in the 4th quarter. The Steelers struggled to move the ball all night and were only able to string the winning drive together with the aid of several boneheaded or questionable penalty calls on the Chiefs. The team's re-energized running game stumbled against Kansas City, who played a spirited game on defense. Derrick Johnson was especially active, disrupting nearly every Steelers run. Wind and rain made it tough for both teams to get their passing games going. Roethlisberger only completed 9 of 18 passes for 84 yards and Leftwich went 6 for 14 for 73 yards. The Chiefs struck first, driving quickly down the field during the opening posession of the game. It was Kansas City's first lead all season. They tacked on a field goal in the 2nd quarter to go up 10-0 before the Steelers answered with a 35-yard kick by Shaun Suisham. Pittsburgh tied the game up on their next posession when Roethlisberger hooked up with Mike Wallace for a 7-yard touch down pass. Wallace caught the ball between his knees and managed to pull it in just before going out of bounds. Despite Kansas City's turnover issues this year, the Steelers weren't able to make any splash plays on defense prior to Timmons' game clinching pick. They did limit Matt Cassel's effectiveness, despite only sacking him twice. That's not saying much, though, considering Cassel has been terrible this year and deep threat WR Jon Baldwin left midway through the game with an injury. It wasn't the dominant performance most expected from the Steelers defense tonight. Some weeks in the ultra-competitive NFL you have to win ugly. Let's hope tonight's game was a case of the Steelers "winning ugly" and not the team regressing back to their earlier season issues. The biggest concern -- especially with next week's game with Baltimore looming -- is Roethlisberger's status. He is more vital to the franchise now more than ever. Update: ESPN reported the Roethlisberger was seen leaving Heinz Field during the game, headed to a local hospital with his wife to have the shoulder evaluated.
