Cherries winger Luis Sinisterra is set for a period on the sidelines after sustaining a hamstring strain.
In a mid-international break press conference, Andoni Iraola revealed that the forward had returned from international duty after picking up an injury with Colombia.
The head coach said: “Sini’s injured; he has a hamstring strain. He will be out, I don’t know, four or five weeks at least.
“It’s a shame for us because he’s someone who we had a plan with him, and it has been working perfectly all season.
“He’s had no injuries and been available all season for us.
“I’m sure Colombia also wanted to keep him with no injuries but he got an injury training with them.
“He came back because they were close, they were in London, so we have already made assessments and he has a strain.”
