Chris Kirkpatrick of *NSYNC was entirely Pete Rose‘d in the middle of a celebrity softball game … receiving leveled at residence plate and breaking his hand in the method — but somehow, the dude kept playing by means of the injury!!

TMZ is told … the musician was one particular of a number of significant names invited to participate in the Rock ‘N Jock fundraiser for Folds of Honor in Nashville on Monday — and at one particular point in the friendly competitors, CK proved just how difficult boy bands can be!!

The moment went down in the third inning … when neighborhood radio host Jeremy Loper rounded third base and headed for residence.

Kirkpatrick was defending the plate, but Loper was out for blood (pretty actually) … pummeling his opponent as he attempted to earn a run.

In the clip of the aftermath, Kirkpatrick is shown hugging Loper to make positive he knew there have been no difficult feelings … but it really is clear the singer can really feel a bit of discomfort when he daps up a different dude — ’cause he promptly pulls his proper hand back to his side.

As for Loper, he showed off his personal concerns — with each his knees oozing with blood as a outcome of the play.

We’re told Kirkpatrick initially believed his hand was just sore, so he toughed it out and played the rest of the game … but when the discomfort lingered a bit, he got checked out by a doc — and positive adequate, he busted his paw.

In spite of the injury, it looked like a effective evening — raising $408,000 for military households … with names like Deandre Hopkins, Taylor Lewan, Charles Esten and Ross Chastain receiving involved in the enjoyable.

Naturally, there was also a moment exactly where Kirkpatrick hopped on the mic and gave the complete stadium a rendition of “Bye, Bye, Bye” … so he definitely was placing it all out there for his group!!
