Ted Rogers was a member of Captain Hopper's crew who transported Professor Parry's expedition to Telos in the 25th century.
He helped detonate the explosives that revealed the doors to the Telosian Cybermen's tombs and was suspicious of the Second Doctor and his companions. When Hopper's ship was sabotaged, the crew repaired it so the expedition could escape Telos. (TV: The Tomb of the Cybermen)
The Fifth Doctor, Tegan Jovanka and Nyssa later found his unconscious body six hours after Hopper's crew left Telos. Hopper and Morton mistakenly accused them of knocking him out. He was later partly-converted into a Cyberman and ejected into space by Morton. (AUDIO: Secrets of Telos)
