"Kym was cleared by the doctor this morning and will be dancing with Hines Ward on the show tonight," her rep, Jane Negline, tells PEOPLE.
All weekend long Johnson rehearsed with Ward while wearing a neck brace.
"Man, Kym is a SOLDIER! She's dancing in her neck brace and will not quit!" Ward posted on his Facebook page Sunday afternoon. "I want to do my best for her because she's busted her tail to get me where I am today. To me, she is one of us and exemplifies the Steeler way. So thanks [for] the prayers and continue to keep voting for us because every point counts. When we get thru this week because of your VOTES, we intend to bring home the Mirror Ball!"
Dancing's other injured performer, actor Ralph Macchio, hobbled through both of his routines last week due to a ruptured Baker's cyst behind his right knee.
But Macchio assured his fans that he's on the mend and ready to return to the ballroom to make his bid for the finals.
"Thanks for asking – yes! Leg is better," Macchio Tweeted Sunday.
Four couples remain in the competition and will compete on Monday's show, which airs (8 p.m. ET) on ABC.
