Ellis Harrison's stoppage-time header earned a much needed but scarcely deserved win for Portsmouth at Doncaster.
Doncaster dominated the attacking play but found themselves behind to a Gareth Evans strike.
Reece James looked to have rescued a point with an equaliser only for substitute Harrison to loop in a header to snatch the win.
Alfie May rattled the bar for Doncaster, beginning a period of attacking dominance but they struggled for clear-cut chances.
Kieran Sadlier turned a shot narrowly wide with his thigh in the best of their first-half opportunities.
Kenny Jackett switched to a three-man front line for the second half but Doncaster continued to dominate.
Portsmouth however took the lead on the hour when James misjudged a clearance allowing the visitors to break with Evans slamming a shot home.
Ben Whiteman hit the bar as Rovers continued to push and they found reward when James lashed in a volley on 82 minutes.
But Harrison sent a header over Seny Dieng in added time to give Portsmouth the win.
