The Spanish right-back has been one of Albion's star performers this season, but manager Gus Poyet revealed he has been carrying an Achilles problem recently.
Bruno had to be withdrawn during the second half at The Valley and his fitness will be assessed ahead of next weekend's visit of Nottingham Forest.
"He has a kind of tendinitis in his Achilles," said Poyet.
"He's had a few problems so he hasn't been training properly but hopefully it's just a little bit of tiredness. We will have to see."
