Loan signing Jason Euell made his debut for Rovers who also included new signing midfielder Franck Moussa.
Swansea continued their promotion charge with the most comfortable of victories over a Doncaster side decimated by injury.
It was hard not to feel sorry for Rovers’ injury-ravaged squad who, having been thumped 6-0 at home to Ipswich in midweek, then lost the services of Ryan Burge ahead of today’s clash and the influential James Coppinger during the pre-match warm-up.
Sean O’Driscoll was only able to name four substitutes at the Liberty Stadium - a reserve goalkeeper and three centre-halves - but even the latter trio could not have prevented what was essentially a training ground exercise for Swansea in the first half.
Scott Sinclair’s 19th goal of the season gave the Swans an early lead before Ashley Williams doubled their advantage before half-time.
Luke Moore secured the victory from the edge of the area with 12 minutes left.
Sean O’Driscoll admitted his Doncaster side were beaten by the better team.
He said: “It was difficult. We have matched Swansea in the past but we were no match for them here today.
“It was a struggle with 13 players out. But the one saving grace was the players kept going.
“There are 14 games to go but I haven’t got a team. We have been pulling rabbits out of the hat all season but I didn’t have a Plan B today.
“Three of my substitutes were centre-halves. What I am going to do with them? I must have run over a black cat somewhere.”
