UFC light heavyweight champion Jon Jones didn't take kindly to Dominick Reyes calling him bipolar earlier this week.

Jones, who defends his title against Reyes in the UFC 247 main event Saturday in Houston, said during Thursday's media day that Reyes needs to "think before he speaks."

"Do you know how many people in the world are losing their homes, losing their marriages, losing their jobs? Bipolar is something that can come onto you in your later years in life. It's a very serious mental illness," Jones told reporters, including MMA Junkie. "The fact that (Reyes) just rattles stupid ... things like that out of his mouth - it's just, he's an asshole, really."

Jones slammed Reyes in a series of tweets Monday, calling the challenger "delusional" for thinking he's a better athlete than most of the champion's previous opponents.

In response, Reyes called Jones "bipolar or something" during an appearance on "Ariel Helwani's MMA Show" later Monday.

Reyes' athletic accomplishments have been a topic of discussion ahead of UFC 247. The California native was the captain of his college football team, the Stony Brook Seawolves, as a defensive back. Reyes had NFL aspirations but didn't make the league. He also has a wrestling background.

Jones doesn't believe Reyes has the accolades worthy of being considered one of the top athletes he's faced. The Jackson Wink MMA fighter wrote Monday that "being a big fish in a small town for so long has really gone to (Reyes') head."
