Not good news if you were hoping Michael Crabtree would be a difference maker this season.
First, Adam Schefter on Twitter.

Anyone waiting for Michael Crabtree to sign with San Francisco could be waiting a long time. A real long time.

Then Matt Maiocco followed up with this:

In exchange w/ league source last night, said I thought Crabtree would sign Labor Day. His response: "I hope you don't play the lottery."

Good luck getting a better offer next season, Crabby.
