Yahoo! Sports' Jason Cole has been told that $3 million of Michael Vick's $15.5 million salary for 2013 becomes guaranteed on March 11, not February 6 as previously reported. If true, the later date allows the Eagles more time to think things over now that Chip Kelly is on board. It's thought that with Kelly now in town, Vick may be more willing to renegotiate his massive deal and stick around. The quarterback's departure from Philadelphia was once widely viewed as a lock, but it now seems to be less certain.
