Cliff Alexander, the undrafted rookie forward out of Kansas, has been out since early October due to what the Portland Trail Blazers are listing as left knee soreness. According to a report on Wednesday, Alexander may need surgery to fix the issue. From Mike Richman of The Oregonian:

"(Alexander) may be out for longer than expected, according to a report from Jay Allen of Fox Sports Radio. Alexander was initially expected to miss 'a couple weeks' with a bone bruise, but may need surgery after a magnetic resonance imaging (MRI) test on Tuesday revealed he had suffered a setback, according to Allen. The Blazers have yet to make a definitive decision whether Alexander will undergo surgery, according to Allen."

The Blazers signed Alexander to a two-year, minimum contract that provides $100,000 worth of salary protection for 2015-16.
