The 25-year-old has only just returned after 19 months out with Achilles and quadricep injuries and made a 12-minute cameo appearance in last Monday's 1-1 draw against Crystal Palace at Goodison Park.
Gbamin, who cost Everton £25million from Mainz in 2019, suffered the contact injury in training at the weekend and was ruled out of Monday night's clash with Brighton.
