Monday could set the stage for significant transition around the NFL, with a laundry list of coaches and general managers resting on the hot seat. NFL Network’s Michael Lombardi and Jason La Canfora visited the “NFL GameDay Morning” set on Sunday to share what they’ve heard about the changes to come.

Multiple players have workouts and tryouts around the league on Wednesday.

Calvin Johnson will play for the Lions on Sunday against the Chiefs, according to source with knowledge of the situation.

Arian Foster’s return to the Texans won’t mean the end of Ben Tate’s role, according to sources.

With kickoff of Week 2 hours away, the playing status of some prominent names is coming into clearer focus.

He is now set to make $1 million in 2011, with $400,000 available to him in incentives. Ginn had been set to make $1.4M in base salary in 2011, with up to $2.9M in escalators, and had a $1.8M base for 2012.

On the hunt for some depth in the secondary, the Miami Dolphins gave tryouts to defensive backs Mark LeGree and Darcel McBath on Wednesday, according to a league source. And in another free-agent visit, the St. Louis Rams tried out defensive back C.J. Wilson.
