Chelsea confirm new injury scare before Sunderland as Xabi Alonso issues Emi Martinez update

Martinez training with protective mask after jaw surgery, ahead of schedule; Caicedo has discomfort from Man Utd match. Alonso will decide on both after Saturday's session.

Chelsea manager Xabi Alonso will use Saturday's final training session to determine whether goalkeeper Emi Martinez and midfielder Moises Caicedo can feature against Sunderland on Sunday. Martinez has been recovering from jaw surgery faster than expected and has been training this week wearing a protective mask, while Caicedo experienced discomfort during the previous match against Manchester United and had a disrupted training week. Alonso said both players are progressing well but the club's medical staff will assess them before making final selection decisions. Jorrel Hato remains unavailable and will miss the Sunderland fixture, with Alonso indicating it will take several more weeks for the defender to return to fitness.
