Catcher Miguel Olivo was suspended Wednesday after biting off part of minor-league teammate Alex Guerrero's left ear during a dugout altercation the previous day in Salt Lake City.
Olivo, who was sent by the Los Angeles Dodgers to Triple-A Albuquerque a week ago, will remain on the suspended list pending the completion of an investigation, the team announced.
Guerrero was taken to a hospital after the incident on Tuesday night and could be out for a month or longer after undergoing plastic surgery.
The Cuban infielder signed a $28 million contract with the Dodgers during the winter.
Olivo, who left the Miami Marlins without permission last year and was placed on their restricted list, has not commented publicly since the fracas took place. Guerrero refused to file a complaint after it happened, according to Salt Lake City police.
Guerrero, 27, played for the Dodgers during their season-opening trip to Australia, but has been with Albuquerque since the Triple-A season began. Olivo, 35, was sent to the minor leagues by the Dodgers last week when A.J. Ellis came off the disabled list.
Tuesday's disagreement began on the mound during an Albuquerque pitching change in the bottom of the seventh inning. The Los Angeles Times reported Olivo was upset that Guerrero, who was playing shortstop, failed to tag out a runner after a throw from Olivo.
The argument continued in the dugout, and the altercation ensured. Both players were removed from the game.
Guerrero is hitting .376 with 10 home runs and 29 RBIs for Albuquerque. He is hitting .457 with six homers in the past 11 games.
Infielder Alex Liddi returned from extended spring training to replace Olivo on the Isotopes' roster.
