Input: Question: How many days after he broke his leg did Port Vale defeat the Bristol Rovers? Passage:He joined Third Division club Port Vale in October 1987, manager John Rudge splashing out £20,000. Scoring on his debut at Vale Park in a 2–1 win over Bristol Rovers on 19 October, he was soon a big hit, becoming the club's joint-top scorer in the 1987–88 season with 10 goals (along with Darren Beckford). He played 48 league and cup games in 1988–89 but broke his leg in a 1–1 draw at Bolton Wanderers on 25 April 1989, and so missed out on the play-off final victory over Bristol Rovers. He managed to recover, but did not re-capture his first team position and in March 1990 was loaned back to Peterborough United, who were then under Mark Lawrenson's stewardship; Peterborough paid £40,000 for his services on a permanent basis the next month.
