Remove author name from excerpt

Hi, I like the way this plugin works a lot; there’s one tweak I’d like to make, though. I’m using the widget to display related posts with excerpts; and I’m using the Biographia plugin to display the author name and avatar under each title. But the excerpt output from Related Posts by Taxonomy starts with the author name and number of posts (“By Phil HillMore Posts (464)”), which is just repeating the information provided just above it. Can the excerpt be displayed without this information, i.e., just the excerpt itself with no author name/number of posts?

Thanks!
