Larry Bird had been bothered by back problems for years, and his back became progressively worse. After leading the Boston Celtics to a 29–5 start to the 1990–91 season, he missed 22 games due to a compressed nerve root in his back, a condition that would eventually lead to his retirement. He had off-season surgery to remove a disc from his back, but his back problems continued and he missed 37 games during the 1991–92 season. His past glory would be briefly rekindled, however, in a game that season in which he scored 49 points in a double-overtime victory over the Portland Trail Blazers. During the 1992 Eastern Conference semi-finals against the Cleveland Cavaliers, Bird missed four of the seven games in the series due to those recurring back problems.
