Belfast boxer Carl Frampton claims opponent Chris Avalos' mother threw chewing gum at him during Friday's weigh-in.
Things got heated after the fighters had stepped on the scales with Avalos shoving the IBF Super Bantamweight champion.
Frampton later tweeted: "Thank you for the amazing support as usual. On another note, Avalos' mother hit me with a bit of chewing gum straight out of her mouth. Lovely lady she is."
