Dillon Danis claims he's still feeling it after his brawl at UFC 322 ... to the point where he won't be able to attend his deposition in his Nina Agdal case next week.
According to court documents, obtained by TMZ Sports, the MMA fighter says he is currently in California "seeking medical treatment" for a head injury he sustained at MSG after throwing hands with several members of Islam Makhachev's team on Nov. 15.
As a result, the fighter's lawyer says Danis won't be around to get grilled by Agdal's lawyers next Tuesday in New Jersey.
