I hope it's not bad, but it says he won't be available for England because of a hamstring injury. Hamstring injuries are not good, I had one myself. It could be just a precaution, I hope so. https://www.bbc.co.uk/sport/football/56543022
We've got decent depth up top right now with ESR, Pepe, and Martinelli. No need to rush him back. He's looked gassed the last few weeks.
True, I hope it's not an injury that will drag on for him, it would be great to see him get some game time at the Euros.
