[11] Finally, Lemsagam sold the football club to local businessman Frank Rothwell in July 2022,[12] at which time Rothwell announced that he was also in advanced discussions to purchase Boundary Park from Blitz,[13] a transaction which completed on 24 March 2023,[14] bringing the football club and its stadium back under single ownership for the first time in over ten years.

When Portsmouth manager Frank Burrows declared that Oldham could not play away from home, Royle stuck the article to the dressing room door and the team responded with a 4–1 victory.

At the end of the 1990–91 season the club secured promotion to the top flight, the final match on the plastic pitch was probably one of the most memorable games played at the ground when Latics, in order to win the old Second Division, had to beat Sheffield Wednesday and rely on West Ham losing.

The additional height has allowed for a supporters bar, offices, corporate hospitality, retail opportunities and a gymnasium.

Following the club's relegation to non-league football with the match against Salford City abandoned, Oldham Athletic decided that the now renamed ‘Joe Royle Stand’ would be closed for the 2022-23 season, on cost and safety grounds.
