Ballack happy after Chelsea comeback
The 31-year-old came off at half-time and will resume training with the first team on Thursday after they have returned from the Champions League trip to Rosenborg.
"It's my first 45 minutes for a long time," Ballack told Chelsea TV. "I feel good. It's a long time to wait because of injury so I am happy to be back.
"You are a little bit careful. I'll train next week and see how it is, then maybe have another game in the reserves.
"I'm looking forward to playing in the first team."
