Ryan Garcia served up one last bit of weirdness. The 140-pound contender, who is scheduled to face Devin Haney on pay-per-view Saturday at Barclays Center in Brooklyn, lost the right to fight for Haney’s WBC belt when he came in 3.2 pounds over the division limit Friday morning. Then, at the public (unofficial) weigh-in in the afternoon, he gave professionalism the middle finger by removing his shirt and chugging down what appeared to be a beer on stage. The fighters later faced off for one final stare down, which was intense but relatively uneventful. Garcia (24-1, 20 KOs) has been acting erratically during the lead-up to the biggest fight of his career, including a series of bizarre and crude comments at the final news conference on Thursday.
