Leeds United manager Jesse Marsch has confirmed Luis Sinisterra has a hamstring injury but hopes it will not keep the winger out for long.
Sinisterra went off with the problem during a 1-1 pre-season draw with Crystal Palace in Perth, Australia.
The 23-year-old Colombia winger signed for Leeds from Feyenoord this summer in a deal reportedly worth £21m.
"Luis had a little hamstring injury. We're hopeful it's not too much, too long and too severe" said Marsch.
"Every time we have a hamstring injury I am totally dissatisfied because it is reflective of everything we do with them physically."
