Atleti face Real Madrid in the European Cup clash in Lisbon on Saturday - with both forwards injury doubts having come off injured in last weekend's league decider against Barcelona.
Costa, who has scored 27 goals in La Liga and eight in the Champions League this term, left the field of play following a recurrence of a hamstring injury while Turan came off with a pelvic complaint.
But in their last training session before they left for the Portuguese capital, the pair played a part along with the rest of the squad.
The Spain international is hopeful that the horse placenta treatment he underwent in Belgrade this week will cure his hamstring tear in time for the match.
Turan's bruised hip has healed quicker than expected but the Turkish international remains a risk should he feature.
Later in the day during pre-match media obligations, both Turan and Costa were participating once again in light training in front of gathered media, including Eurosport's own Tom Adams:
