Diego Simeone oversaw a session for his fringe players at Majadahonda on Thursday with Kevin Gameiro joining in with the group.
The Frenchman had sat out the games with Granada and Bayer Leverkusen due to abdominal pain but worked out alongside Stefan Savic and Nico Gaitan ahead of Atleti's LaLiga fixture at home to Sevilla.
Those who began the 0-0 draw with Bayer Leverkusen underwent a recovery session in the gym before Simeone ran over some defensive drills with Filipe Luis, Savic, Gabi, and Juanfran ahead of Sunday's match.
