He sat out the next two games and returned in Week 4 against the Vikings, but he was still visibly hampered, most evidently when he was unable to chase down Vikings defensive lineman Alan Page during a 65-yard fumble return. Sayers carried only six times for nine yards before further injuring his knee. He underwent surgery the following week and was deemed out for the remainder of the season. He had carried 23 times for 52 yards to that point. During his off time, Sayers took classes to become a stockbroker and became the first black stockbroker in his company's history. He also entered a Paine Webber program for 45 nationwide stockbroker trainees and placed second highest in sales. After another knee operation and rehabilitation period, Sayers attempted a comeback for the 1971 season. He was kept out of the first three games after carrying the ball only twice in the preseason, as Bears head coach Jim Dooley planned to slowly work him back into the rotation. His first game back was against the New Orleans Saints on October 10, in which he carried eight times for 30 yards. After the game, he told reporters he was satisfied with his performance and that his knee felt fine.

He was encouraged to retire but decided to give football one last try. Sayers' final game was in the 1972 preseason in which he fumbled twice in three carries; he retired from professional football days later.

He possessed raw speed and was also highly elusive and had terrific vision, a combination which made him very difficult to tackle.

Mike Ditka, a teammate of Sayers' for two seasons, called him "the greatest player I've ever seen. That's right—the greatest." Another former teammate, linebacker Dick Butkus, famous for his tackling ability, said of Sayers: He had this ability to go full speed, cut and then go full speed again right away. I saw it every day in practice. We
