Game 5 of the 1991 first-round series against the Indiana Pacers might not be the most elegant or important game of the original Big 3 Celtics era. But this game has lived on in Celtics lore for one reason: Larry Bird’s incredible return from smashing his head on the parquet floor. The 34-year-old Bird had missed 22 games that season due to a compressed nerve and ruptured disc in his back and the pain had gotten so bad that he spent the night before Game 5 in traction in the hospital. When Bird had back surgery after the season was over, the surgeon said, “I don’t see how he played with what he had.”
