The Brazilian was introduced at halftime and made an impact against the Black Cats as he scored the equaliser, but he was replaced after picking up a knock, which Andoni Iraola confirmed was a dead leg.
But the striker faces a late assessment to see if he can feature against the Bees on Tuesday night with a quick turnaround between games.
Giving an update in his press conference on Monday afternoon, Iraola said: “I don’t really know, it’s still too early.
“The only thing I can tell you, yesterday he didn’t train, he still was very sore, but we train this evening, so I hope he comes with better feelings and he gives a try at least, and let’s see where he is.
“He’s not injured, it’s just a knock, he has a dead leg, but obviously we are talking about one or two days and still he’s a little bit sore, yes.”
