Tells us a bit about your project......
Have you exposed the entire joist along its length?
Is it a rot problem you have - and if it is, could there be more than one joist affected?

Where is the joist (e.g. nearest the wall at one end), what is wrong with it and how is it supported? Basically if you really do need to replace a joist you'll need to cut a track out of the floor between the joists either side of the defective one to gain access to the area s you can work on it. What you then discover in terms of how the joint is supported will probably dictate the method of replacement
