But when when you go off and perform vigorous exercises you repeatedly contract those muscles and pull on those tendons, if there's micro tears in the tissues than this is likely to increase the chances of damage and injury.

I bet after playing/training your calves will be TENSE, the last thing you want is tense muscles pulling on tendons that have been temporarily weakened by stretching.

Really it could be a number of things, but probably the first to rule out is stretching when cold and before vigorous exercise and over stretching.
That makes sense, I have pulled my calf by over stretching which I have never ever done before. Stupid stretching never used to do it before. Will try just warming up. Feel better already. Thanks.
