While the injury that kept Kendrick Perkins off the court for Game 7 of the NBA Finals was initially described as a torn MCL and PCL, Danny Ainge has revealed that the Celtics believe that Perkins has a torn ACL as well—a condition which could make him miss part of the 2010-2011 season.
Nothing will be known for sure until Perkins actually has surgery, but ACL injuries carry much longer recovery times than MCL and PCL injuries. With only four months separating the end of the Finals and the beginning of the next season, it’s hard to imagine Perkins being ready for the start of the season if it is an ACL injury.
