Here are the most interesting stories Thursday in the AFC North:
After suffering a season-ending shoulder injury as a rookie, former first-round pick Rashard Mendenhall should get his share of opportunities in the Pittsburgh Steelers' preseason opener against the Arizona Cardinals.
Morning take: Mendenhall's role will be as large or as small as he makes it this year. He can begin earning playing time by impressing Pittsburgh's coaching staff with a good preseason debut.
Tempers flared in Baltimore Ravens camp between cornerback Frank Walker and receiver Yamon Figurs.
Morning take: Training camp fights happen all around the league, especially this time of year when teammates are tired of pounding each other and it's time to play some other teams.
With a lot of hype surrounding the team, the Cincinnati Bengals are just one day away from their preseason debut against the New Orleans Saints.
Morning take: This will be quarterback Carson Palmer's first game in nearly a year. It will be interesting to see how he responds after taking his first hit.
Cleveland Browns quarterback Derek Anderson says he's staying relaxed despite his competition with Brady Quinn.
Morning take: If Anderson wants to win Cleveland's starting quarterback job, it's a must that he stays loose. When Anderson played nervous and uptight two years ago, he couldn't beat out Charlie Frye in training camp.
