Assign numbers with decimals from a line to a variable

I am trying to assign a string of numbers with their decimals to a variable. The code reads a file called 'log'. I have not included the entire file since it's huge.

The line is:
Code:
 Tagging release with the label program-2.8.114...

My code:
Code:
BUILDNUMFORSIT=$(egrep 'Tagging release with the label program-' log | grep '[0-9]\{1,\}.[0-9]\{1,\}.[0-9]\{1,\}')

My output:
Code:
BUILDNUMFORSIT=' Tagging release with the label program-2.8.114...'

My desired output:
Code:
BUILDNUMFORSIT=2.8.114

Please help!Smilie
