In a tweet by Panthers beat writer Joe Person, it has been reported that the Panthers have designated recently released LB James Anderson as a post-June 1st cut. This means that only $1.4M of his accelerated bonus money will count towards the 2013 salary cap, and his 2014 cap figure will be $2.8M.
It was speculated that the Panthers would just eat the entire cap hit in 2013 since it was only $4.2M, because doing so would create more cap relief in 2014 with Anderson's bonus money completely off the books. Why they decided to split the cap hit into two payments is not known at this time, though it could signal another move that the organization has yet to make.
Cutting another player is entirely possible, as the team can designate two players for post-June 1st status. There are quite a few contracts on the books that the Panthers may try to get themselves out of, so stay tuned for any updates on this situation.
