Leicester City manager Craig Shakespeare says Kelechi Iheanacho’s injury is nothing to worry about as the player will soon be back to full fitness.
The 20-year-old left the pitch just 18 minutes after coming on as a 66th-minute substitute for fellow striker Shinji Okazaki, following a collision with the German side's Laszlo Benes.
"He's fine in there. He's getting a bit of a ribbing from the players in terms of him coming off.
"You can see the impact he's had. We're just really making sure that was more of a precaution. He hasn't trained very often, he hasn't been able to because of circumstance.
"The more minutes he can get on the pitch, the more liable he will be to last 90 minutes."
Two goals from England striker Jamie Vardy enabled Leicester to come from behind and win the game 2-1.
The Nigeria international only joined the club on Thursday from Manchester City.
