| 1998 | L | Jim Bacon | — | ADCC World Championship |
| 1998 | W | Jim Bacon | RECONSTRUCTED: printed QF box reads 'Simon Siasi' as the winner over the Joe Charlesus/Jim Bacon pairing, but Simon Siasi is shown losing his own R16 match to Jim Bacon earlier on this same poster. Same recurring pattern as 77kg SF1 and the 2013 Absolute Gary Tonon case - an unannotated substitution. Bronze-match box independently confirms Simon Siasi (not Jim Bacon or Joe Charlesus) reached the next round. Recorded as Simon Siasi def. Jim Bacon since Siasi's only printed opponent on this side of the bracket was Jim Bacon. | ADCC World Championship |
