Giovanni van Bronckhorst confirmed the Scottish side’s news on the eve of the showdown in Seville, striker Roofe having last played just over a month ago, and he starts on the bench in Spain.
“Kemar is available,” said the manager.
“He trained for the first time with us [on Monday]. He had individual training before that and he will be training later. He will be in the squad and if I want to use him he is available.”
Alfredo Morelos is still absent due to a thigh injury, along with long-term absentees Ianis Hagi and Filip Helandar. Aaron Ramsey had to settle for a spot on the bench.
Ryan Jack starts in midfield for Rangers, in their first European final since facing Zenit in 2008.
