Suns F Tom Gugliotta still is bothered by headaches apparently caused by a spinal tap performed after his seizure Dec. 17 and has not rejoined the team.

Team doctor Richard Emerson initially said Gugliotta could be back for last night's game against the Warriors.

But Coach Scott Skiles said before the game that Gugliotta will work his way back more slowly because the headaches are persisting.

"I think he feels pretty good when he wakes up in the morning, and as the day goes on, he's not so good again," Skiles said.

Skiles said he doesn't know when Gugliotta will come back.

"From what I've heard, most of these things are remnants of the spinal tap, not from what happened to him," Skiles said. "I've heard it can just clear up instantly or whatever."

Gugliotta suffered the seizure on the team bus following a victory over the Trail Blazers in Portland, Ore. The spinal tap, a CT scan and an EKG were performed at a Portland hospital and showed no abnormalities.

Gugliotta returned to Phoenix the following day and since has undergone a series of tests.

He has missed five games and likely will not be with the team for games at Utah today and against the Lakers in Los Angeles on Wednesday.
