1915-07-05 (158/160lbs) Jack Dillon drew 10 George Chip, Association Park, Kansas City, Missouri, USA. Referee: Walter Bates. Made at 158lbs, the Kansas City Star reported that with the men inside the limit Dillon risked his title claim at the weight. Having to make the weight by 3pm weakened both, the first six rounds seeing little action. This was the tenth meeting between the pair, and first one man looked to get his punches off and then the other, with little between them. After having a good ninth round Chip was looking to build on that in the tenth, but Dillon's rushing tactics forced him on to the back foot where he had to use all of his experience to extract himself from several difficult situations.
A few days later, on 12 July, at Brown’s Gym, Queens, NYC, New York, an over-the-weight Dillon scored a ten-round press win over Johnny Howard, who weighed in at 160lbs. In the aftermath, Dillon, finding it increasingly hard to make 158/160lbs anymore, campaigned as a light heavy.
