In reply to bpmclimb:
I did the same injury and followed the rehab programme to the letter and it worked a treat. After the rest phase, there was some gentle calf stretching to get ROM, both with leg straight and knee a little bent. Then a period of doing heel raises (repeatedly going up on your toes), then small hops, then eventually full on hopping on one foot going round in a square (forwards side, back, side) X 5 reps, 3 sets. The physio did soft tissue massage to get the knots out and promote good healing.
Some where along the line i was advised to start doing 10 minute jogs too.
I was told 4-6 weeks, this was bang on.
