Palmer’s performance against Brentford was Palmer’s 13th appearance of what has been an injury-plagued campaign so far and was just the fourth time he has completed 90 minutes under both Enzo Maresca and Liam Rosenior.
Fans were worried that the England star would not be ready to face Pafos after the 23-year-old was spotted clutching his groin shortly after the full-time whistle against the Bees.
However, football.london report that Palmer was on the grass with his teammates at Chelsea's training base in Cobham and looked fine throughout the session, which is a huge boost for Rosenior and his side.
Chelsea are two points off the automatic last-16 places with two games to go and are competing in their fourth different tournament in the space of four games as Rosenior is pushed to the limit in his first few weeks at the club.
Palmer’s comeback from a groin injury that kept him out for over two months, from September to December, has restricted his game time and performances this season.
He is unlikely to start against Pafos but could feature off the bench late into the game as Rosenior tries to build his match fitness for what remains of the season.
