Russian gymnast Artur Dalaloyan, a presumptive medal contender in the men's contest at the Tokyo Olympics, tore his Achilles tendon in preparation for the upcoming European Artistic Gymnastics Championships, Russian outlet TASS reported Friday.
"Unfortunately, Arthur was injured during a control training session with an Achilles tendon tear," Russian head coach Andrei Rodionenko told TASS.
Dalaloyan, 24, underwent surgery and is expected to make a full recovery in three months, Rodionnenko said. That timeline leaves uncertainty regarding his prospects for the Tokyo Games, which begin in just over three months.
"Doctors give favorable forecasts, they give three months for a full recovery. We continue to rely on this athlete," Rodionenko said.
Kirill Prokopyev will replace the three-time world champion at the European Championships, set for April 21-25 in Basel, Switzerland.
Dalaloyan -- the 2018 world all-around champion -- is seeking his first Olympic berth. Along with 2019 world all-around champion Nikita Nagornyy, Dalaloyan was expected to bolster his nation's quest for its first team gold medal since 1996.
