Marquez (thumb) threw a bullpen session Saturday, Patrick Saunders of The Denver Post reports.
Marquez exited Wednesday's game against the Dodgers due to a cut on his right thumb, but he said following Saturday's throwing session that the issue is fine. The Rockies haven't officially indicated whether the right-hander will be able to make his next turn through the rotation, but he tentatively lines up to start on the road against the Dodgers if he's cleared to pitch.
