Wilfried Kanon had to be substituted before the end of the first half of the away match against FC Groningen with a hamstring injury.
The Ivorian defender was subjected to additional investigations on Monday morning and it appeared that the damage was not too bad. However, it is not yet possible to estimate how long the injury will take to recover.
Kanon quickly seized his hamstring in Groningen after a defensive stretch and was subsequently treated on the sideline. The International player of the Ivory Coast then played on, but had to be replaced in the fortieth minute by Shaquille Pinas.
