1. Michael Schumacher's return to competitive F1 racing might be a tad surprising, but not at all shocking.
2. The maverick three-time Formula One world champion is arguably the greatest comeback story in the history of sport.
In 1976, Lauda, the defending world champion then, crashed at the German Grand Prix and his Ferrari burst into flames.
3. Thomas Muster after being injured severely came back to court and His win at the 1995 French Open made him the first from his country to win a major, the top spot soon followed and 39 more titles were added to the kitty.
4. When at the peak of her career, with as many as eight major titles in just three years, Monica Seles was attacked and stabbed by a deranged Steffi Graf fan when she was playing in the German Open in 1993. The subsequent injury cost her two-and-a-half years on the professional circuit and Graf added to the major tally in the meanwhile. Seles made a brave comeback though and added the 1996 Australian Open title to her trophy cabinet.
5. In October 1996, Lance Armstrong, just 25 then, was diagnosed with stage three testicular cancer that had spread to his lungs, abdomen and brain. The American had an orchiectomy to remove his diseased testicle but chose an alternative treatment to avoid the lung toxicity. He went on to win the Tour de France a record-breaking seven consecutive years, from 1999 to 2005, retiring after his final triumph.
