regex - sed - Replacing from string to end-of-line -

this should incredibly easy can't work. want use sed replace 1 string end of line. example if have following data file:

   1  2  3  5    4 2  5 five 6    6  1  2 7 4

and want replace word "two" through end of line word "blah" ending output:

   1 blah    4 blah    6 1 blah

wouldn't be:

   sed -e 's/two,$/blah/g'

i'm not best @ regex maybe that's problem

this should want:

sed 's/two.*/blah/'

$ echo "   1  2  3  5 >    4 2  5 five 6 >    6  1  2 7 four" | sed 's/two.*/blah/'    1  blah    4 blah    6  1  blah

the $ unnecessary because .* finish @ end of line anyways, , g @ end unnecessary because first match first two end of line.
