He later had an MRI exam on his back so that the Sixers could determine whether Hawes' body was in proper alignment. That exam also came back negative.
After Hawes missed 11 games from Jan. 16 to Feb. 4, he returned for games against Atlanta and the Los Angeles Lakers.
Going into Wednesday, the Sixers were 12-2 in games with Hawes and 8-7 in games without him. Hawes is averaging 10.5 points and 8.3 rebounds this season.
Thorn spent a good part of Wednesday afternoon on the phone with Hawes and his agent, Greg Lawrence, and they decided that now is a good time to have a specialist look at the injury.
"That's what you always do with a player if he's not coming on as well as you'd like for it to be going," Thorn said. "You get a second opinion, and that's what we're going to do."
Iguodala on Howard
While the Sixers don't appear to be a likely landing spot for Orlando center Dwight Howard, Sixers forward Andre Iguodala talked about what Howard brings to Orlando and what he will bring to his new team when he is, as most believe he will be, traded at the trade deadline.
"He's one of a kind with what he brings to the table," Iguodala said. "He makes it so easy for that team defensively. You can have a lot of liabilities around him and he can cover for them - that's a great luxury to have.
"Offensively he opens it up for the shooters," he continued. "That's why they have four shooters surrounding him at a time because you have to help on him. You have to double-team him if he gets it going. It's kind of like picking your poison when you go up against a guy like that."
