On the upcoming episode of 'Dancing With the Stars', the world renowned competitors will battle each other in the Semi-Finals round this Monday night.

'Dancing with the Stars' will start at 8:00 pm ET and can be watched online through live stream via the link provided below.

On tonight's episode, there are reports 'Fresh Prince of Bel-Air' star Alfonso Ribeiro might be forced to retire from the competition despite a successful run on the long running dance competition series due to a recent back injury (in addition to a previous groin injury).

"Hey #TeamWitfonso thanks 4 all the love. I'm working really hard to be able to dance Monday. Keep the prayers coming. Love you all," wrote Ribeiro via Twitter on November 15.

Ribeiro previously revealed the how his current groin injury affects his performance in a very candid interview.

"I feel like I can't do 100 percent. I can't get it to that next level. I feel like I'm delivering 85 percent rather than 100, because I know that if I go harder then I'm going to injure it more. I have to give it half energy until performance night, and then I turn it up," said Ribeiro to TV Guide.

"The difference is that, anytime you do something where you don't have the ability to know what that turning up feels like ahead of time, when you get on that stage for performance, it's unknown. So there's a little bit of discomfort in that. ... When you have a tear in your groin, it's not comfortable to take steps."

On last week's "Dynamic Duos Night" episode, 'Back to the Future' actress Lea Thompson and her dance partner Artem Chigvintsev were eliminated from the competition in Week 9 on November 10.

After the recent elimination, the stars who are still in the running to win the dance competition's ultimate prize, the Mirror Ball trophy, are as follows: Sadie Robertson, Bethany Mota, Tommy Chong, Janel Parrish, and Alfonso Ribeiro.
