Cech must wear a protective helmet and chin strap to ensure his safety against further head injuries.
The Czech Republic stopper has already called this his 'worst season' ever in terms of getting hurt - but he can see a possible silver lining.
He said: "I'm now really happy and enjoying every moment.
"I've been quite unlucky this season with injuries and I couldn't wait to be back.
"Some people say I look a bit funny with my head guard and the chin strap but, if I have to play with all my face covered, I'd be happy.
"I'm just happy to be on the pitch."
