STOCKHOLM, Sweden (AP) _ Per-Ulrik Johansson, a member of the European Ryder Cup team who was forced to withdraw from the World Cup of Golf last month, still does not know what caused his dizzy spells.

``Of course I'm scared,'' Johansson said Wednesday. ``It's tough not knowing what's wrong.''

Johansson, a member of the European Tour, was to play in the PGA Tour's qualifying tournament this week but was forced to withdraw because the dizzy spells persisted.

Johansson, 31, said he was seeing doctors every day at a hospital in his hometown of Uppsala, about 60 miles north of Stockholm. His fellow Swedes Joakim Haeggman and Niclas Fasth, meanwhile, are at tour qualifying school, a six-day tournament which started Wednesday in Haines City, Fla.

``Golf is not important now,'' Johansson said. ``I just hope to get well so I can spend time with my family during Christmas.''

Johansson's dizzy spells started during the Sarazen World Open in Georgia the first week of November and finally forced him to pull out of the World Cup at Kiawah Island, S.C., the next week.

``They made all kinds of tests but found nothing,'' Johansson said. ``Maybe it's all stress. I've been traveling a lot this fall,'' he said.

Johansson won twice on the European Tour this year and finished 11th on the final European money list.
