The goalkeeper took a blow to the head from Reda Johnson moments after spilling Miguel Llera's corner into his own net to gift Wednesday their second goal in a 3-1 win.
Jakupovic was stretchered off in a neck brace and taken to hospital for tests.
Rob Price, Hull's head of medical services, told the club website: "Eldin received treatment for a facial injury on the pitch, and was taken to the stadium's medical room on a spinal board as a precaution.
"At no time did Eldin suffer any loss of consciousness, and he was completely responsive throughout.
"He was then taken to Hull Royal Infirmary for further examination, where all results thankfully came out as normal.
"Hull City AFC would like to thank all paramedics involved and medical staff at Hull Royal Infirmary for their work."
