Saturday links: Four retire as Steelers

A look at what's happening around the division:

BENGALS: Defensive end Robert Geathers could be sidelined for the entire preseason. Geathers injured his left knee on the first day of training camp and had it scoped Friday. Carlos Dunlap replaced Geathers in the starting lineup.

BROWNS: New owner Jimmy Haslam indicated that he's open to keeping team president Mike Holmgren around for the 2012 season. "I don't anticipate becoming owner until the middle of October," Haslam told the Cleveland Plain Dealer. "We have until the middle of October to listen and learn. You're basically halfway through the NFL season there, so that's reality."

RAVENS: Center Matt Birk could miss Thursday's preseason opener after being sidelined for a fifth straight practice with back spasms and a knee injury. "I'm probably going to slow him down a little bit more especially this week and maybe next week after the game, get him back in there," coach John Harbaugh told the Baltimore Sun. Rookie fourth-round pick Gino Gradkowski is expected to fill in for Birk at center.

STEELERS: Joey Porter, Willie Parker, Aaron Smith and Marvel Smith all retired as Steelers before the team's annual night practice. "This is home. Even when I left -- it was OK to go and play for Miami and Arizona ... but there's nothing like home," Porter told the Pittsburgh Post-Gazette. "Pittsburgh -- once you come through here -- it's a special piece in your heart here, in Pittsburgh. That void wouldn't have been filled if I didn't come back and retire as a Steeler."
