(NEXSTAR) – Bo knows ... when you're talking about him. It might have seemed that way Friday when former star NFL tight end Tony Gonzalez called his fellow Kansas City ball player "mean," adding, "he's not very nice." To be fair, Gonzalez was giving high praise – referring to Bo's demeanor running the football – but his sudden appearance had Nexstar's Simone Eli joking, "He's about to come running through this table right now!" When Jackson – a legendary two-way player – came over and sat down, Gonzalez told him how he idolized him as a 7th grader ... before throwing Eli and co-host Chris Hagan right under the proverbial bus. "They also said you were very mean, a very mean person," Gonzalez joked. "I said you were really nice, I swear to God!" Eli responded, as Jackson scowled over at them. The Raiders star took it in stride, telling Nexstar, "I am mean," before joking, "Once you get past 60 you can take all the filters off, you say what you want. You can be mean when you want, cause you can always blame it on 'Hey, I played football,'" Jackson said, tapping the side of his head. During his playing days, Bo Jackson's achievements were mind-bending. An All-Star in both Major League Baseball and the NFL, some may remember the time he broke a bat over his own head, or the play when he literally ran up a center field wall, or the time he ran 91 years for a Raiders touchdown and continued straight into the tunnel. No longer running around – or through – obstacles on the field, Jackson has a new goal. The former NFL and MLB great told Nexstar he is a cancer survivor – something he announced publicly only this week – emotion creeping into his voice as he explained that he had his prostate removed in October, and is working to spread awareness among other men. Jackson, wearing a hat emblazoned with BKMH (Bo Knows Men's Health), told Nexstar, "I don't think God put me on this Earth just to play sports."
