Lee Sang-yeol of KB Insurance's men's volleyball player, who was controversial due to the assault of Park Cheol-woo, eventually resigned.
Manager Lee Sang-yeol said he apologized to Park Cheol-woo and volleyball fans for improper behavior 12 years ago, and that he would withdraw from his position to take a moment of self-sufficiency.
In 2009, coach Lee assaulted Park Cheol-woo, who was the coach of the national team, and was suspended indefinitely, but returned to the scene after being released from discipline after two years.
Recently, as Park Chul-woo showed strong rejection to social media, the assault incident 12 years ago and the discipline of a cotton bat became controversial again, and the director eventually stepped down.
KB Insurance's coach Lee Kyung-soo leads the rest of the season.
