USC WR Jordan Addison pulled himself from position drills Saturday at the NFL Scouting Combine because of a minor back strain. It's not expected to affect his readiness for the school's pro day. Before leaving, Addison posted a 4.49-second 40-yard dash and a 34-inch vertical jump. Neither mark proved especially impressive for the 5'11, 173-pound wideout. We'll see whether the testing numbers affect his NFL Draft outlook. And we'll have much more on the former Biletnikoff Award winner as we preview all the fantasy-relevant rookies over the next two months.
