Both players have been struggling of late but Giuseppe Biava returned to his teammates today in training after recovering from his hip problem.
Mauri has a bruised right thigh so sat out of training as a precaution so as not to overload the impact on the injury. He is hopeful for the game against Catania.
Klose is recovering well and was running today and returned to do some physical exercises. Floccari on the other hand is working in the water to try and recover in time for the Derby.
