Norwich City manager David Wagner has confirmed striker Josh Sargent will be out for "months" rather than weeks with the ankle injury he suffered against Huddersfield at the weekend.
The American was helped off the pitch after scoring the first goal in City's 4-0 win, with what was described at the time as a "serious" injury.
Wagner says Sargent will find out if he needs surgery after seeing specialists.
The 23-year-old has scored three goals in four Championship games this term.
Speaking after Norwich's 1-0 win at Bristol City in the second round of the Carabao Cup on Tuesday, Wagner told BBC Radio Norfolk they are starting to know more about the likely prognosis of Sargent's injury.
