If the report by Person isn't enough, we also have a tweet from the man himself:
#PantherNation I'm back for another year! We're grinding to the top!— Jordan Senn (@JordanSenn57) March 6, 2013
Terms of the deal are currently unknown, but unless the Panthers gave Senn a Charles Johnson type deal this is a smart move. Senn is a great contributor on special teams (he is the ST Captain, after all), and a good rotational linebacker who has definitely earned a spot on the 2013 roster.
Yes, the Panthers are still over the salary cap, but it's a guarantee that they will be under it by the March 12th deadline. Even though they still have some trimming to do, I don't expect Senn's deal to cost that much towards the cap. According to Spotrac his contract for the 2012 season was for $765K, so while he may get a slight bump in pay I don't expect him to get more than $1M to remain in Carolina in 2013.
Stay tuned to CSR for the details of Senn's contract, which we will provide as soon as they are available.
