The Korean Football Association has said Heung-Min underwent a successful surgery on his broken right arm on Friday and will take about a month to recover.

"The operation was successful," KFA Spokesman Cho Jun-Heon told AFP, adding that Son will stay in South Korea to focus on his recovery.

Son, 24, left the field in obvious pain in the 33rd minute of South Korea's 3-2 World Cup qualifying defeat to Qatar on Tuesday, clutching his right forearm after an aerial challenge.

The operation at a university hospital lasted about an hour, and Son had the broken bones repaired with pins and metal plates to keep them in place, the Sports Chosun daily reported.

While the KFA estimated Son's recuperation would take about a month, Song Jun-Seop, a former national team doctor, gave a longer recovery time of at least 12 weeks.

The new Premier League season kicks off in eight weeks' time, on August 12, and South Korea have crunch World Cup qualifiers on August 31 and September 5.
