For all the Rockets' changes, forward Bonzi Wells' availability for training camp remains the same.
For the second straight season, a groin injury is expected to keep Wells, 31, off the court through the Rockets' six days and seven practices in Austin.
"We've known about it a little while, and were hoping it would clear up by this time," Rockets general manager Daryl Morey said. "Bonzi's got a minor groin issue that looks like it's going to keep him out for some time. We're not sure how long at this point.
"I think any player who has been injury-prone in the past is more likely to be injury prone in the future. We want Bonzi here from day one, but the fact is, he can't go right now."
Wells, 6-5, played 28 games last season, averaging 7.8 points on 41.1 percent shooting.
Rockets athletic trainer Keith Jones said Wells' injury is not as serious as the tear that limited him through much of the 2005-06 season with Sacramento or even the soreness that kept him out for much of his first preseason with the Rockets. But Jones said he expects Wells to be out at least a week.
"He'll do some cardio stuff off the court," Jones said. "There's nothing torn like there was. We'll move slow. The first week or so, we'll do nothing on the court, just cardio stuff and rehab."
