Swansea lost their 100% home record in the Championship after being held to a goalless draw by Derby at the Liberty Stadium.
Brendan Rodgers' side edged the first half but struggled to break down a resolute Derby defence in a disappointing encounter.
Stephen Dobbie twice came close for the Welsh side and Craig Beattie had two late chances to win it, while Derby also had their chances in the second half but the game always looked destined to finish goalless.
A point for Derby stretched their unbeaten run to three matches.
But Nigel Clough's side are without a win on their travels since the opening day of the season.
