 Sheehy is one of two NHL players who wore the number 0, the other was Paul Bibeault.After NHL statisticians discovered a bug in their new stat-tracking software, the league restricted jersey numbers to whole numbers between 1 and 99 (later limited to numbers between 1 and 98 after the league-wide retirement of number 99 for Wayne Gretzky), giving Sheehy the distinction of being the last player in NHL history to wear number 0 for the Hartford Whalers in 1988.His older brother is former NHL and USA Olympic team member Timothy Sheehy.
