Jesus clipped Fernandes just outside Arsenal’s 18-yard box, causing Fernandes’ boot to come loose.
The United midfielder then twice threw his boot to the ground in frustration at referee Andrew Madley deciding against rewarding a free kick, earning him a booking for dissent. However, while Fernandes fumed, Jesus stayed down and required a stretcher.
Jesus is the latest injury to one of Arsenal’s starters, with Bukayo Saka ruled out until March after he required surgery on a hamstring injury.
Arsenal are also without Ethan Nwaneri (muscle injury), Takehiro Tomiyasu (knee) and Ben White (knee).
