Grant McCann made just one change from the starting XI at Hull, with captain Richard Wood replacing Tom Anderson, but too many players struggled to replicate their midweek heroics.
Here’s how we rated the Rovers players after a bad day at the office.
5. Joseph Olowu - 4
Robbed of the ball inside his own box for the first goal and must take a share of the blame for the third. Photo: Dave Lofthouse
6. Owen Bailey - 4
Couldn't deal with Newport's attacking threat and gave away possession cheaply once or twice. Subbed off after 30 minutes. Photo: Howard Roe/AHPIX LTD
7. Harrison Biggins - 4
Did nothing of note all afternoon. Firing a free-kick from a good position straight into the stand behind the goal summed it up. Photo: Howard Roe/AHPIX LTD
8. George Broadbent - 4
Booked for fouling a Newport player in frustration. Together with Biggins, completely lost the midfield battle against Aaron Wildig and Bryn Morris. Photo: Howard Roe/AHPIX LTD
