Brooklyn Nets star James Harden is not one to back down in any challenge, even if it's from a former NFL star in Chad Johnson.

On Sunday, Johnson revealed his latest generous act, tipping $1,300 to his server in Harden's Thirteen Houston restaurant. On the receipt he posted though, he wrote that the Nets guard is “scared” to play him in FIFA.

James Harden saw the incredible act and showed his appreciation for the “love” from Chad Johnson. Of course, he also didn't let the call-out slide and fired back, noting that it was actually the ex-Cincinnati Bengals wide receiver who has been running away from him for years now.

“Lol and we can line the FIFA up any day. You been running for some years now,” Harden hilariously shared in response to the challenge.

Well, this is certainly a match-up that everybody would want to see. Maybe the two can stream their game for everyone to see and so we can know who destroyed who?

Besides, should the Nets be able to close out the Boston Celtics on Tuesday in their first-round playoffs clash, Harden will have plenty of time to play Johnson–not just one game but maybe more!

For no, though, Nets fans will probably want The Beard to focus on the task at hand and send the Celtics back home as they continue their journey to the NBA title.
