Tottenham have received a boost ahead of their Champions League last-16 first leg clash at Wembley.
When asked whether Reus would be ready for Saturday's league meeting against Hoffenheim, Dortmund coach Lucien Favre said: "We don't know yet. I can't answer that definitely. We will have to wait some days and examine him again.
"[Wednesday] will be too early so we will have to wait a day longer, but we hope."
