The 20-year-old striker had to leave the field on a stretcher, just 17 minutes after entering the his side's eventual 2-0 loss as a second-half substitute appearance on Saturday.
“We think he has broken his leg. We are not absolutely certain but it looks that way," Doncaster manager Darren Ferguson said.
"I think it had a big impact on the result. My players were visibly shocked and you could see the boy was in a lot of pain.
"He signalled straight away and it is a real shame for the boy. He is a lovely lad and to have such a serious injury. He is currently in hospital."
Thanks for the messages, find out the full extent of the injury in coming days, but I'll be back better & stronger. pic.twitter.com/0kAlMFnrG1
