According to the Willamette Week, Dr. Craig Nichols was put on administrative leave and his contract was not going to be renewed in July.

He helped treat Armstrong, who survived testicular cancer and went on to ride the Tour de France seven victories.

Neither Nichols nor the hospital gave a reason for the decision, the paper said.
