The midfielder broke down durig their FA Cup win at Sunderland.
Howe said: "The big negative today is Joelinton.
"We don't know what that injury looks like, but we did have some training time and we had a chance to get the players in a much better physical position for this match today.
"It looks like as he was switching the play, he felt his thigh, so we'll wait and see."
