Free-agent guard Evan Mathis said the Ravens have offered him "a nice deal" but the team didn't get the response that they expected -- he left town.

Mathis hasn't turned down the offer, but he has decided to go back to Arizona to think it over. Teams prefer to get the deal done before a player leaves, so it's hard to gauge how this is going to turn out.

It's quite possible that Mathis is going to give the Eagles a chance to match the offer. Eagles general manager Howie Roseman said the team is still interested in keeping Mathis.

“We’d like Evan back and we’re in constant communication with his representatives,” Roseman said.

The Ravens need Mathis because he is the best free-agent option remaining to fill the void left by Ben Grubbs, who joined New Orleans yesterday. But Baltimore will be wary of overpaying a 30-year-old lineman.

Here are some midday notes of what's happening in the AFC North:

• The Bengals let Dolphins defensive end Kendall Langford leave town without a contract and have turned their attention to Colts defensive end Jamaal Anderson, who is visiting Cincinnati today. Comment: I thought the Bengals had a good shot with Langford, who would be the preferable choice over Anderson.
• Joe Flacco's agent, Joe Linta, had another meeting with the Ravens about a contract extension and said talks about the quarterback are "moving in the right direction." Comment: Don't get your hopes up. This isn't going to get done anytime soon.
• The Ravens lost their fourth player in free agency when backup safety and special teams standout Haruki Nakamura agreed to a three-year contract with the Carolina Panthers. Comment: Baltimore could still bring back free-agent safety Tom Zbikowski, but team officials would have preferred to keep Nakamura, who was one of coach John Harbaugh's favorite players.
• The Ravens could be on the verge of losing their fifth player: inside linebacker Jameel McClain is visiting the Denver Broncos today. Comment: This is why the Ravens gave a second-round tender on restricted free-agent Dannell Ellerbe.
• Bengals starting left guard Nate Livings is continuing his free agent tour, going from Dallas to St. Louis today. Comment: Livings is getting a lot more attention on the free-agent market than I anticipated.
