Cincinnati's Michael Johnson couldn't believe how quickly the afternoon disappeared as the visiting Bengals a shared practice with the Atlanta Falcons.

The defensive end says he enjoyed almost everything about Monday's change of pace in the Bengals' training camp. "It was fun," Johnson said before adding the 90-degree Georgia heat was a factor.

Bengals coach Marvin Lewis and Falcons coach Mike Smith also liked the first of two days of shared practices before the teams meet in their first preseason game on Thursday night.

Lewis says he'll have "great tape to evaluate" as he makes decisions on roster spots.

In an attempt to guard against injuries, there was no tackling to the ground. Smith had no update on Falcons linebacker Sean Weatherspoon, who left practice early.
