Sky Bet Championship leaders Norwich had to settle for a 1-1 draw as battling Rotherham left Carrow Road with a hard-earned point.
The Canaries, beaten 1-0 at home on Tuesday night by a smash-and-grab raid from Charlton, failed to convert their early chances before Rotherham went ahead on 44 minutes through a penalty from Paul Green.
Norwich upped the tempo following the restart as the Millers sat back, and were level when Cameron Jerome knocked in a rebound after a free-kick from substitute Kyle Lafferty was saved.
Neil Adams’ men pressed during the closing stages, but were unable to find a winner and, for 24 hours at least, remain top of the table.
Rotherham should have taken the lead on eight minutes when a free-kick was headed back from the near post by Kari Arnason, but the ball got stuck at the feet of Matt Derbyshire, who, just a yard out, could only stab it straight at John Ruddy.
