Captain Terry sustained an ankle injury in last week's semi-final first leg with the Spaniards in Madrid, which ended 0-0, forcing him out of Sunday's 2-0 Premier League win over Liverpool.
Belgian winger Hazard has been sidelined since suffering a calf injury in the Champions League quarter-final second leg win over Paris Saint-Germain on April 8 but both players are expected to play at Stamford Bridge tomorrow.
Of Hazard, Mourinho said: "He is ready. It's my option whether he starts or not, but he is ready."
It was also confirmed that Terry would start as he looks to lead the west London club into the May 24 final in Lisbon where they will meet Real Madrid if they can successful navigate the visit of Atletico.
