Juan Carlos Navarro sustained a foot injury during Spain's tournament-opening win over China on Sunday.

"It was very strong and all of a sudden,'' Spain coach Sergio Scariolo said. "It is nothing related with his former problems. It is a probably a new injury. It is plantar fasciitis, but it is probably in a different place [within the foot].

"He couldn't play. I don't know how many games he will miss.''

Without Navarro, Spain rallied behind Pau Gasol for an 82-70 win over Australia on Tuesday.

"He's not obviously too happy right now because he's injured and he couldn't play today and we don't know exactly when he's going to be able to play,'' said Gasol. "It's not the easiest situation for an athlete to go through during an Olympics.''

Erik Spoelstra wants to make sure history doesn't repeat itself.

"If we learned one thing from the 2006 title, it was that you need to continue to reinvent yourself and improve as a basketball team," Spoelstra said. "That year we brought the exact the same team back, we thought it would be the same path and same journey. It never is.

"It's always going to be different. And we ended up losing the first round and we were swept in four games. Another year later, we only won 15 games and we were the worst team in basketball and that's how fragile this game can be."

Miami signed Ray Allen and Rashard Lewis to add depth and three-point shooting to a rotation that includes Shane Battier, Mike Miller and James Jones.

Maalik Wayns has signed a one-year contract with the Sixers.

“It’s going to be a great experience for me, I’m just so happy and excited that things worked out the way they did,” said Wayns, who went undrafted in June. “I was confident that I was going to catch on with somebody. I knew I was going to play in the NBA. I just didn’t know where.”

Wayns averaged 11.7 points, 5.7 assists, 2.3 rebounds during the Orlando Summer League.

“I thought I played well in Orlando and there were rumors going around that a team or two were looking to sign me,” said Wayns. “But nothing happened. Still I never lost confidence that things would work out. The Sixers talked to my agent (Andy Miller) and we got a contract. I was thinking the whole time of just going to training camp and trying to make a team, really without any security. This is an added bonus.”

C.J. Miles, according to a source, is drawing serious interest from the Lakers.

Miles, who has already met with the Mavericks and Cavaliers, could make a decision within the next 2-3 days.
