According to the Boston Herald, which first reported the deal, Turner will sign for a portion of the midlevel exception.
Boston is adding the former No. 2 pick from the 2010 draft. But the 25-year-old Turner will be looking to revitalize his career in Boston.
Turner has averaged 11.1 points, 5.3 rebounds, and 3.1 assists over four NBA seasons. He was dealt from Philadelphia to Indiana at last year's trade deadline with the playoff-bound Pacers looking to bolster their bench. Turner played only sparingly as a reserve while Indiana was bounced in the Eastern Conference finals.
