Swansea keeper saves penalty on debut
Doncaster remain rooted to the foot of the Championship after Dimi Konstantopoulos saved a late penalty on his Swansea debut.
Rovers had the chance to secure a late victory but on-loan Coventry goalkeeper Konstantopoulos kept out Paul Heffernan's effort from the spot.
Jason Price could not find the net with three good chances as Sean O'Driscoll's side were left to rue a string of missed opportunities.
O'Driscoll must have feared the worst when his side nearly fell behind inside the opening seven minutes. Angel Rangel jinked half the length of the field past a clutch of Doncaster players before shooting low past goalkeeper Neil Sullivan and inches wide. At the other end, James Hayter blazed an ambitious 25-yard volley over as both sides showed plenty of early attacking endeavour.
Swansea midfielder Mark Gower will feel he should have at least hit the target from 12 yards when gifted a clear sight of goal following good link-up play with Jason Scotland after 20 minutes, but the former Southend man scuffed his effort over.
A defensive mistake from Ashley Williams on the half hour then almost proved costly for Swansea.
Brian Stock's punted clearance from inside his own half bounced over Williams and Price seized on the loose ball before unleashing a rasping angled drive from the edge of the penalty area which just cleared the crossbar.
Price - who also spurned several gilt-edged chances during Tuesday's 1-0 defeat against Barnsley - went agonisingly close again moments later, turning and shooting from 35 yards with Konstantopoulos relieved to see the ball roll wide.
Problems
Shortly before half-time, Ferrie Bodde rippled the side-netting after directing Gower's cross goalwards, while Lewis Guy fired over from 15 yards.
It was Price who continued to cause Swansea no end of problems after the restart as a Martin Woods corner was eventually diverted into his path by Mark Wilson, but the towering Doncaster forward shot low and wide.
When Price did have the ball in the net from close range after 61 minutes following Matt Mills' flicked header, it was disallowed for offside.
Sullivan had to be alert to gather Scotland's well-struck shot through a crowded penalty area with 20 minutes remaining, while Darren Pratley and substitute Guillem Bauza also wasted clear-cut chances for Roberto Martinez's Swansea.
Darren Pratley was first put through on goal by a superb raking pass from Scotland but, after a poor first touch, failed to hit the target and Bauza also lashed over with virtually his first touch.
The home side, with time running out, were then awarded a controversial penalty five minutes from time as Pratley was adjudged to have handled in the box has he tried to meet Woods' corner.
Heffernan stepped up to take the spot-kick but his low effort was saved by Konstantopoulos and his weak header from the rebound was also kept out by the Swansea goalkeeper.
A fine one-handed save from Sullivan denied Bauza in a thrilling finish.
