Pulisic strained his right quadriceps in an exhibition against Chile on March 26 at Houston. He scored in the fourth minute, then left late in the first half. Pulisic has been limited to 15 league matches and 25 overall this season for Borussia Dortmund. He tore a calf muscle last October and a thigh muscle in February, and lost playing time because of the emergence of 19-year-old English winger Jadon Sancho.
Second-place Dortmund, which is one point behind Bayern Munich, hosts Mainz on Saturday.
