Jalisco authorities have issued an arrest warrant for Tapatio boxing sensation Saul “Canelo” Alvarez just days before his next big fight.

On Wednesday, April 17, the state Prosecutor General’s Office ordered Alvarez’s arrest for allegedly attacking fellow boxer Ulises “Archie” Solis in October 2011. Solis claimed that Alvarez accused him of involvement with his girlfriend and then attacked him at a Guadalajara training facility, leaving him hospitalized with a broken jaw and a cracked tooth.

Alvarez denied the allegation at the time, claiming it was his brother Juan Ramon Alvarez who attacked Solis. A warrant has also been issued for the brother, who stands accused of supplying false information to the police.

This is not the first time that members of Alvarez’s family have been in trouble with the law. Another of the boxer’s brothers, Victor Manuel Alvarez Barragan, is wanted for the alleged murder of Luis Enrique Gama Partida at a party in the family’s home town of Juanacatlan, just outside Guadalajara, last November.

Alvarez is currently in Texas preparing to fight U.S. boxer Austin Trout in front of 30,000 fans in San Antonio’s Alamadome on Saturday night. The case will not disrupt the fight but it will come as an unwanted distraction as Alvarez prepares for one of the toughest contests of his career to date.

Both boxers are undefeated, with Alvarez putting his WBC light middleweight champion title on the line and Trout reciprocating with his WBA super welterweight champion belt.
