Norris (finger) was able to play catch off flat ground Wednesday, Jordan Bastian of MLB.com reports.
Norris has started up his throwing program after landing on the 15-day injured list just under a week ago with a left index finger strain. He doesn't look like he'll be in store for a long-term absence, though the Cubs may not have much urgency to rush him back. The lefty has been handling a low-leverage role out of the bullpen all season and has submitted a 7.24 ERA over his 24 appearances.
