The Bears captain was on hand Wednesday morning to watch practice at Halas Hall.
A report in The Chicago Tribune said, in May or early June, Urlacher went to Germany to meet with a doctor, presumed to be Dr. Peter Wehling, about regenokine treatment, a procedure that uses the patient's blood to speed the healing of a knee joint.
The procedure is not approved by the FDA.
Urlacher and Coach Lovie Smith neither confirmed or denied the story Wednesday.
Urlacher would only say: "I was definitely in Europe last year."
