Southend United winger Sam Barratt is set to be out "long-term" after picking up a knee injury in training.
The 22-year-old joined the League One side from Maidenhead in May and made his EFL debut in their opening-day defeat by Doncaster on 4 August.
Shrimpers boss Chris Powell said he is not yet sure exactly how long he will be without Barratt.
"Sam's got a knee injury which looks long-term. It's a real disappointment for him," Powell told BBC Essex.
