From the Panthers site:
The Carolina Panthers have claimed tight end Marcus Freeman, quarterback Matt Moore and tackle Frank Omiyale off waivers from Baltimore, Dallas and Atlanta respectively, the team announced Sunday.
Well, that's the risk. I didn't think it would happen, and the Cowboys probably didn't either.
That prompted this note from KFFL:
Cowboys | Bartel signs to practice squad
KFFL has learned the Dallas Cowboys have signed unrestricted free-agent QB Richard Bartel (Cowboys) to their practice squad.
Hat tip to Philosopher for pointing it out in the comments.
