Buckingham was praised earlier in the season after wearing jumper that highlighted the importance of men’s mental health on the touchline, during his team’s game against Burnley at the Kassam Stadium.
The stadium played host to Monday’s event, where people were able to find out about local support and chat with like-minded people.
Buckingham told the BBC: “If we can play our part as a football club to raise awareness of what support there is, then we have to do that.”
He continued: “Football, traditionally, has always been a very much, ‘this is how you do what you do’, and men don’t talk about that sort of stuff.”
