Nine-times Korea international defender Hong Jeong-Ho is the latest high-profile footballer to be implicated in the K-League match-fixing scandal.
Jeju United defender Hong, who is the captain of Korea's Olympic team, has been questioned by prosecutors investigating the widening scandal.
The 21-year-old sat out Jeju's league match against Gangwon on the weekend.
"Hong told us last Friday that he had nothing to do with the case," said a K-League official to Yonhap News.
"For the time being, we told Jeju to keep him on the bench."
Jeju United spokesman Kim Dong-Nam told AFP that Hong denied any wrongdoing.
However, prosecutors have said they believe Jong was involved in Jeju's 5-1 loss to FC Seoul last year.
Last week, former national team forward Choi Sung-Kuk, who is currently with Suwon Bluewings, came forward about his connection to the scandal.
