Jimmy Butler's decision not to participate in the All-Star game rubbed some people up the wrong way and caused a bit of controversy.The Minnesota Timberwolves star chose to sit out the showcase game in order to rest his body for the second half of the season.Some people felt that the shooting guard should've given up his spot to a player that actually wanted to play.One of those players could've been Los Angeles Clippers veteran Lou Williams.He's enjoying a career year in L.A. and was unfortunate not to be selected for his first All-Star appearance.Williams openly expressed his frustration at missing out by taking to Twitter to post some cryptic tweets.The 31-year-old also had something to say about Butler's decision to stay on the bench for the entire game and not take to the floor.In a tweet directed at the T-Wolves man, Williams said: "u serious bruh? Lol."

A lot has been made of this reaction by the Clippers guard and it inevitably got back to Butler, who is not one to stay quiet.

When asked for his reaction, the three-time All-Star issued a challenge to Williams and anybody else who has a problem with him not playing in the game.

"To Lou and to whoever else thinks they're an All-Star, with all due respect, LeBron (James) and them got $100,000 for winning," Butler told ESPN's Cassidy Hubbarth.

"So if you've got $100,000 to put up, and we play one another, you guard me and I guard you, I'm going to show you why. All this talk, put $100,000 up, and I'll show you why and where I'm at."

The Clippers' sixth man scoring machine appeared to backtrack on his previous tweet by stating that he was only merely trolling his counterpart and didn't really care if he played or not.

Butler also mentioned how being tasked with guarding James Harden in the Timberwolves' first game back after the break played a part in his decision.

Ironically, however, the former Chicago Bulls star suffered a scary knee injury in the encounter on Friday night and had to be carried off the floor in Houston.

Thankfully for Minnesota, the X-rays came back negative but he's due to undergo an MRI on Saturday to determine the full extent of the injury.

A lengthy layoff could have a serious impact on their season and they'll be hoping for the best case scenario.
