NFL Commissioner Roger Goodell is still reviewing the gun-related arrests of Cleveland Browns defensive linemen Shaun Rogers and Robaire Smith, Mary Kay Cabot of the Cleveland Plain-Dealer reports.

Rogers was arrested in April after attempting to carry a loaded weapon onto a plane at Cleveland Hopkins International airport. Rogers was unaware that gun was in his bag, and last month was placed in a 12-month diversion program.

If he completes the program, which consists of firearms safety training and community service, the charge will be dropped.

Smith was stopped at Bishop Airport in Flint, Michigan last November when a gun was discovered in his carry-on bag. Smith forgot that the gun was in his bag, and after an investigation, Smith was charged last month with misdemeanor possession of a firearm in a sterile area of a commercial airport.

Smith's case is still pending, which may explain the delay in the players' punishment under the league's personal conduct policy.

"It's a clear mistake," Goodell said. "It is a violation of law. It's the kind of judgments that we have to make sure we do a better job of avoiding."

Gooden and John Madden arrived at the Browns' headquarters in Berea, Ohio on Thursday.
