Falkirk's unbeaten home run in all competitions is over after Morton won 2-0 at The Falkirk Stadium.
The threadbare Bairns rarely looked threatening in the league game, and goals from Archie Campbell and Michael Tidser gave the Greenock club three vital points in their battle against relegation.
Steven Pressley returned to the touchline after his ban but his influence couldn't propel Falkirk to victory, and the club have fallen off Ross County's tails with just one point from a possible 12.
Jordan White was replacing Farid El Alagui in attack and should have given Falkirk the lead moments before the deadlock was broke.
White was inches from connecting with a Tam Scobbie cross and Morton charged up the park and a Tidser effort squirmed through Michael McGovern and into the net.
Substitute Rhys Bennett made a difference for Falkirk replacing makeshift right-back Stewart Murdoch, but though he hit the post Falkirk seemed destoned not to score and Campbell stroked a second for the visitors with eight minutes to go.
Falkirk's only consolatrion from a disappointing night is Dundee's defeat in Hamilton. The Bairns remain level on points with the Dark Blues in joint second.
