"I'm back in training and feel 100 per cent so I'll be ready for the start of the season at Sunderland," Aurelio told the club's official website.
"It was really important for me to be involved in the pre-season training camp in Switzerland and I worked hard. Unfortunately another small problem kept me out when I got a kick on my shin which caused some inflammation, but I'm now looking forward to the start of the season.
"It will be the manager's decision whether I will be involved against Sunderland. I hope to do a good job and help the team make a good start to the season."
Philipp Degen is facing at least another week on the sidelines.
