When Broncos rookie wide receiver Demaryius Thomas left Tuesday's practice with more pain in his left foot, there was at least some concern he had suffered a stress fracture that could potentially have kept him on the sideline for three to four months. However, initial tests, including X-rays and a magnetic resonance imaging (MRI) exam, indicate Thomas did not suffer a stress fracture, but he is still in doubt to play in the Broncos' regular-season opener Sept. 12 in Jacksonville Thomas, who fractured the foot in a pre-draft workout in February, was evaluated to attempt to locate the source of the discomfort he felt in his surgically-repaired foot when he returned to practice Tuesday. Thomas had been out 17 days since the team's Aug. 7 practice in Invesco Field at Mile High. During that stadium practice he had an issue with scar tissue around the area of his original fracture, a common aftereffect of the injury and the usual surgery to repair it and his latest bout could involve some additional scar tissue.
