Chelsea duo Petr Cech and John Terry have trained with the squad ahead of Wednesday's Champions League semi-final second leg against Atletico Madrid.
Goalkeeper Cech had been expected to miss the rest of the season after dislocating his shoulder during last week's 0-0 draw in Spain.
Blues captain Terry was also a major doubt due to an ankle injury that he picked up at the Vicente Calderon.
Meanwhile, Eden Hazard and Samuel Eto'o have also trained following spells on the sidelines with calf and knee problems respectively.
