 On December 11, 1905, before the start of the 1905 – 06 season, Stuart was suspended from the league after the western teams complained that he had won too many championships and was too rough for the league. He was reinstated by the league on December 30, and joined the Pittsburgh Professionals. After Pittsburgh finished their season, Stuart joined Calumet for one game so they could try to win the league championship, which they lost to the Portage Lakes Hockey Club. Once again he was named best cover-point in the IPHL as he scored eleven goals. A big man with a fluid skating stride, he was considered the finest defenceman of his era for his outstanding play on both offence and defence.
