Micah Johnson is a common denominator in a highly uncommon scenario.

Johnson, still a force as a 37-year-old Saskatchewan Roughriders defensive tackle, has been a teammate of Benny Sapp III and his father.

Benny Sapp II and Johnson both played for the NFL’s Miami Dolphins in 2010. Sapp III joined the CFL’s Roughriders on Aug. 19.

“It tripped me out!” Johnson said. “When we signed him and we kept hearing ‘Benny Sapp III,’ I was thinking, ‘I know that name …’ I had to go and make sure.

“My rookie year with the Dolphins, I made the 53-man roster down there. Three or four weeks in, we had some trouble with the nickel position, so they brought Benny’s dad in.

“I remember we clicked instantly. He was my guy back then. He was a hell of a ballplayer. He made all the difference for the team that year. I was messing with (Sapp III), saying, ‘If you’re anything like your daddy, I know you’re nice.’ ”

Confirmed.

“It’s a small world and football is a brotherhood,” Sapp III said in his friendly fashion.

“It’s crazy. I’m not going to lie. I didn’t expect that at all. That was the last thing on my mind coming here.

“Micah came up to me the first day and I fell to the ground, just in disbelief. I couldn’t believe it. I’m not going to lie to you. I didn’t know what to do.

“It’s amazing and it really helps me keep my head on my shoulders. It lets me know how privileged I am to have an opportunity to even do something like that. I’m truly blessed for it.”

Sapp II, now 44, was an NFL cornerback with the Kansas City Chiefs (2004-07), Minnesota Vikings (2008-09, 2011) and Miami (2010-11).

He registered six interceptions in 110 regular-season games, 27 of which he started.

Sapp III emulated his father by making it to the NFL as an undrafted player out of Northern Iowa, suiting up five times for the Green Bay Packers in 2023.

While playing safety, he cemented a roster spot by making an interception in the Packers’ pre-season finale.

“I feel like I’m doing something my dad helped me out with,” said Sapp III, 25, who hails from Fort Lauderdale, Fla.

“Growing up, he was giving me bits and pieces of what I can attain every year, and it got better and better. He even coached me my last year in college.

“Just having him as a support system and somebody I can have as an open book who has been there for multiple years, it gives me more hunger. It helps me understand that the formula actually works.”

Jokingly, Sapp III was asked if he was a defensive back by birthright.

“I’ve got a quick little funny story for you,” he replied with a smile.

“In my Little League games and in middle school and stuff, I was playing linebacker and running back. Then, one day, my dad asked me if I really wanted to play football. I told him, ‘Yeah, Dad, I really want to play.’

“The next day, I kid you not, he told me a time to wake up. I made sure I was there and we started doing defensive back drills. I’ve been doing defensive back drills since I was 10, 11 years old.

“He definitely got all the cracks and all the nicks out for me at a young age. I appreciate it a lot.”

He also appreciates paternal advice that continues to this day, early in his CFL journey.

“My dad has just been telling me to keep taking it day by day,” said Sapp III, who made his CFL debut on Saturday when the Roughriders played host to the Montreal Alouettes.

“I’m being welcomed back to my natural position. He always taught me corner growing up. I played safety when I went to college, so this is my first time getting played at the position that I learned football from. He’s just really excited about that.

“He just told me to trust my keys and be who I am. Now it’s time to show this part of the world who we are.”

Two worlds converged in August, when Sapp III and modern communications technology enabled Sapp II and Johnson to reconnect.

“I actually let them FaceTime each other,” Sapp III said. “The first week I was here, I let them talk to each other. They were chopping it up.

“I was just sitting there watching, thinking, ‘Bro, this is crazy.’ ”

Considering Johnson’s remarkable longevity, it is crazy to ask whether, one day, he will be on the same team as, say, Benny Sapp IV.

“I don’t know, man,” Johnson, who with five games remaining has already equalled last season’s total of six sacks, said after laughing uproariously.

“I’ll have to stop playing one day, I guess.”
