Brooklyn Nets guard D'Angelo Russell suffered a knee injury late in the Nets' game against the Utah Jazz in Salt Lake City nearly a week ago, and has not played since. Based on the Nets' latest press release Friday, it doesn't appear he will be back any time soon. The Nets announced that Russell "underwent successful arthroscopic surgery on his left knee." Russell was off to a brilliant start in his first season with the Nets after being traded from the Lakers over the summer. Through his first 12 games with his new squad, Russell averaged 20.9 points, 5.7 assists, and 4.7 rebounds while shooting over 46 percent from the field -- all of which would be career-high marks.
