The pair slugged it out at Wembley Arena in London on Friday night, with Groves coming out on top via a unanimous decision.
Groves is now on the verge of another world title shot but his main concern was with the Kazakh-born German on Saturday.
“Out of respect to Eduard Gutknecht and his family’s privacy I don’t want to say too much but we were all deeply concerned to hear that he was taken to hospital after the fight last night.
“I sincerely hope it is nothing too serious and I would like to send out all of my support and best wishes to him and his family and this difficult time,” stated Groves.
Initial reports in the UK press are indicating Gutknecht collapsed before ‘needing to be resuscitated in the ambulance’ on the way to receiving care for his condition, with a further update expected from his promoters at Sauerland later this weekend.
Gutknecht, 34, was beaten convincingly despite showing tons of heart in what was his 36th professional contest. Groves won the fight 119-109 on two cards with the other reading 119-110.
