According to The Sun, the 21-year-old singer-songwriter has been asked back to the show to sing on the last episode of the talent contest.
It was confirmed on Saturday (November 3) that Spraggan had pulled out of the competition suffering from ill health.
She had been given a free pass to this weekend's show after not being able to perform the previous week (October 27).
Spraggan said in a statement that passing through two rounds of the competition "would not be fair" on the other acts.
During The X Factor last night, Spraggan's mentor Tulisa said: "She was amazing person to work with. I'm going to miss her very much."
The Sun also claimed that Spraggan's girlfriend Harriet Lichfield has returned from Thailand to be at her side.
