The Teesside flyer was hurt knee-on-knee on the wing for Sheffield in their 1-5 loss to Nomad Astana in Belarus tonight.
He went off after nine minutes and will likely go to a local hospital in Minsk either tonight or tomorrow.
Dowd described his situation as "not fantastic."
More tellingly he said that once he returned to Sheffield he expected it to be a "grind of a recovery."
He said he was massively frustrated by the injury, which came from an opponent who was kicked out of the game.
