Barker injury blow for Pilgrims
Barker, 29, sustained the problem in the warm-up before last week's goalless friendly draw with Hearts at Home Park.
Now he will miss Argyle's Championship opener at Crystal Palace on Saturday and boss Paul Sturrock said: "I'm gutted for Chris. He has trained so hard this summer and I thought he was very competent last season.
"He was one of our top performers and his consistency levels were excellent."
