Wesley Matthews stated during his exit interviews that he expects to resume playing basketball in August.
August is a bit of an aggressive timetable for such a serious injury, but he did say that rehab has been going well and that he's feeling good. Still, players tend to be overly optimistic in projecting their timetables for recovery, and we'd rather hear something from Portland's medical staff before truly projecting his tentative return date. Matthews will be a free agent this offseason, and it'll be interesting to see what kind of salary he can command on the open market coming off a torn Achilles.
