UPDATE- This move is now official, per the team Twitter feed.
Per Ian Rapoport on Twitter, the Carolina Panthers upon finalizing the contract for Daryl Williams this afternoon have released offensive tackle Matt Kalil.
The writing was pretty much on the wall since yesterday that this move was incoming, but some reports earlier today (ironically from the same source) indicated that might not be the case.
Unresolved issue for the #Panthers: The status of LT Matt Kalil, whose $7M salary become fully guaranteed tomorrow.
