The Phoenix Suns and guard Vince Carter have agreed to modify the date on which Carter’s contract becomes fully guaranteed, the club announced today. Originally, the Suns had until Thursday, June 30, but that date has been changed to the start of NBA free agency for the 2011-2012 season.

“This change gives us additional time and flexibility to make a decision on Vince’s contract,” said Suns President of Basketball Operations Lon Babby.

The 6-6, 220-pound Carter was originally acquired by the Suns from the Orlando Magic on Dec. 18, 2010, along with Marcin Gortat, Mickael Pietrus, a 2011 first-round pick and cash considerations in exchange for Hedo Turkoglu, Jason Richardson and Earl Clark. Carter appeared in 51 games (41 starts) following the trade, and averaged 13.5 points, 3.6 rebounds and 1.6 assists in a Suns uniform.
