Chelsea club doctor Bryan English has lamented the 'incredible' bad luck suffered by goalkeeper Petr Cech.
Cech is currently sidelined after he sustained a facial injury in training following a collision with team-mate Tal Ben Haim.
The Czech Republic international, who wears protective headgear during matches after he suffered a fractured skull last season, had only just returned to training since being forced onto the sidelines with an ankle injury.
And English has bemoaned the shot-stopper's recent fortune, telling Chelsea TV: "It was only the second training session since he got back, he's looking good, looking sharp.
"Whether (manager) Avram (Grant) would have selected him to play Fenerbahce I'm not sure but he was available.
"It's just the incredible luck the guy has. But in the end it's a flesh wound and he's going to make a full recovery.
"He's always committed, he's a very professional player and as soon as he feels he's got the go-ahead from the medical team I'm sure he'll be extremely positive about it."
With second-choice keeper Carlo Cudicini suffering a hamstring injury in the UEFA Champions League victory over Fenerbahce in midweek, Hilario will again be called upon to deputise by Grant for Monday's clash against Wigan.
And English is backing the Portuguese to provide solid cover, adding: "On more than one occasion he's come into a very awkward situation and rescued the club.
"He's a very calm customer so you know if we ever do need him he's not going to flap or be in awe of the situation. He's always going to do well for us."
