The rocker and star of The Libertines was recently given a six-month prison sentence after he pleaded guilty to cocaine possession.
According to NME, the official court documents give a likely release date of August 21 that would mean he could headline the Festival Republic stage at the Leeds Festival on August 26.
He is also lined up to play at the Reading Festival on August 28.
A spokesperson for the Reading and Leeds Festivals recently told NME that they had no comment on Doherty's planned appearances.
