striker Jonathan Kodjia could miss the start of next season after breaking his ankle.
The 19-goal forward was forced off in the second half of Saturday's 1-0 defeat at Blackburn and is likely to require surgery.
The Championship club confirmed Kodjia will now visit a specialist in Europe this week for further tests.
Kodjia, 27, joined Villa in a deal worth up to £15million from Bristol City last summer and has kept the club away from relegation danger.
The next highest scorers in the league for Villa this season are Jack Grealish and Rudy Gestede - who joined Middlesbrough in January - with just four goals apiece.
