Liverpool loanee Loris Karius has returned to training after recovering from a muscle injury which ruled him out of action for the past few weeks.
Turkish-Football can confirm that Karius has resumed full team training and is likely to be ruled match fit to star in goal against Goztepe at the Vodafone Park next week.
Karius missed the opening game of the season against Sivasspor on Saturday.

Karius was first-choice keeper for the Black Eagles last season and is expected to keep his role in the side this term.
