Britain had two judokas competing on the same day for the first time in Brazil on Wednesday, after Ashley McKenzie went out on Monday and Colin Oates on Tuesday.
However neither Davis nor Gosiewski could claim a win as both were thrown for ippon despite leading early on in their first matches with Hedvig Karakas and Dex Elmont respectively.
Davis was a waza-ari up on her world debut but was caught by Karakas in the -57kg category while at virtually the same time on a different mat Gosiewski suffered a similar fate in his -73kg contest.
Britain must now wait a day for a chance to alter their fate at the World Championships in Rio with Olympic silver medallist Gemma Gibbons, Sally Conway and Natalie Powell all up on Friday. � Sportsbeat 2013
