Pierre sends Cobblers into the relegation zone as resurgent Shrewsbury shock Doncaster
Cotterill continues fine start at Salop
Cobblers have dropped into the Sky Bet League One relegation zone following Shrewsbury Town's 1-0 win at Doncaster Rovers on Tuesday.
Former Town defender Aaron Pierre scored the only goal of the game when heading home Shaun Whalley's second-half free-kick.
Shrewsbury, who sacked Sam Ricketts and replaced him with Steve Cotterill last month, have now won three games in a row to leap up to 16th in the table.
Cobblers, meanwhile, drop to 21st and have still played more games than the majority of teams around them.
