Back on June 23, YOH went one on one with BUSHI in the first round of the New Japan Cup 2020. The Roppongi 3K member was ultimately unsuccessful in the match and New Japan Pro-Wrestling later announced he had suffered a knee injury and would be out of action for an indefinite period.
The promotion decided not to strip the tag team of the IWGP Junior Heavyweight Tag Team Championship despite YOH's injury and SHO has continued to wear the title to the ring for his singles bouts.
However, with YOH's return date still unclear, SHO relinquished the title in a post-show press conference following night 13 of the Summer Struggle tour in Korakuen Hall. He also stated the team will not be splitting up and they will aim to reclaim the championship once his tag team partner returns.
How NJPW plans to crown new champions is currently unknown.
Roppongi 3K have held the IWGP Junior Heavyweight Championship on four occasions. Their last reign began at Wrestle Kingdom 14 when they defeated Taiji Ishimori and El Phantasmo.
