Here's the official word via a very official looking email from the Suns officials:
LOPEZ INJURY UPDATE
PHOENIX - The Phoenix Suns today made the following announcement:
Suns center Robin Lopez was seen today by specialist Dr. Christopher Huston of The Orthopedic Clinic Association (TOCA) in Phoenix. Lopez, who has missed the club's last eight games due to an injured back, did not receive an epidural and is progressing well. He will continue to undergo rehabilitation and will be re-evaluated in one week.
The second-year player was the Suns' first-round pick (15th overall) of the 2008 NBA Draft. The 7-0, 255-pound center has blossomed after being inserted into the Suns' starting lineup on Jan. 18, helping to lead the Suns to a 22-9 (.710) record in his starts. As a starter, Lopez has averaged 11.3 points, 6.3 rebounds and 1.1 blocks in 24.5 minutes.
For the season, the Stanford product is posting career-highs in points (8.4), rebounds (4.9), blocks (1.04) and minutes (19.3). His 58.8-percent field-goal accuracy (171/291) would rank third in the NBA if he reached the statistical minimum needed to qualify (min. 300 field goals made).
So basically, we continue waiting. At least the news wasn't bad...so that's good.
