Is it possible those are seedlings?
If they are suckers, there are a couple of options, but neither one will be ready by the weekend. First, you can remove it. Dig down as far as you can and clip it from the mother plant. Try to take as many roots along with it. Once out, pot it up, clip the leaves in half and follow Bass' instructions for rooting summer cuttings. I've been leaving the tent on for about the weeks... at least until you see new to growth and then some.
Secondly, create a make shift pot around the sucker. I use the straight part of a soda bottle. Cut two slits at the top and bottom on each side of the bottle. Pass bamboo skewers through the slits so the top of the skewers is even with the top of the bottle. Then, wrap the bottle with foil. Slip the sucker through the bottle and push the skewers into the growing mix. Fill the bottle with the same growing mix and water when you normally water the parent tree. Let it ride until just before it breaks dormancy, then remove and pot up.
