A bad week has turned worse for Adelaide's reigning best and fairest Bernie Vince, with the midfielder injuring his ankle at training.

Vince, along with teammates Graham Johncock and Matthew Jaensch, was already set to miss Sunday's AAMI Stadium clash with Brisbane because of club-imposed suspensions.

But he could have his stint on the sideline extended after he rolled his ankle while being tackled during a competitive training drill on Wednesday and had to be helped from the field by trainers.

If the injury stops the 24-year-old from playing in the SANFL this weekend, his one-match club suspension will be postponed until the following weekend, meaning he will also miss the round 10 clash with St Kilda.
