Huddersfield Town

Newton began his career at Huddersfield Town with the "Terriers" in 1973–74. Newton was named most valuable player in a world youth competition at 17, but suffered two severe injuries that took him off the field for more than two years.^[5] He spent four years at Huddersfield and left to join Hartlepool United in mid-1977 for a fee of £5,000.^[6]

Hartlepool United

He scored eight goals for Hartlepool in his debut season, including both goals in the club's shock 2–1 victory against Crystal Palace in the third round of the FA Cup.^[7]

Off the field, Newton has had two car accidents, including one in 1978 in which his passenger, teammate Dave Wiggett, was fatally injured; he was sentenced to nine months in prison in 1979 after being found Guilty of causing death by reckless driving.^[8][9] After the incident he moved to the United States, playing for the New England/Jacksonville Tea Men in the North American Soccer League in 1980 and 1981.^[5][10]

Newton returned to English football and was well received by fans at the Victoria Ground, and for three years formed a strike partnership with teammate Keith Houchen. In 1981–82, Newton and Houchen each had 18 goals and were Hartlepool's top scorers with Newton scoring a total of sixty goals with Hartlepool.^[11]

Port Vale

In September 1982, Newton was transferred to Port Vale for £15,000.^[6] He went on to become the team's top scorer with 22 goals, while the club achieved promotion to the Third Division.^[12][13] "Valiants" manager John McGrath nicknamed Newton and strike partner Ernie Moss as the "Kray twins" due to their dominance of opposition defenders.^[14]

We were quite a big, physical team and, in Bob Newton, had this barrel-chested striker who just loved a battle with the opposition centre-halves. I hope he doesn't mind me saying that his game was less about finesse and more about blundering the ball into the net – taking the goalkeeper with it if necessary. Don't get me wrong, Bob was a good player, as his 24 goals in 51 appearances suggests. Besides, I had reason to be grateful for his fearsome reputation. When I broke into the team as a naive teenager, any defender who tried to kick lumps out of me would soon get a warning from Bob. He was a cult hero with supporters who loved to see him score goals, and bully defenders. He would sometimes take his false front tooth out to make him look more ferocious. There was nothing underhand or sneaky about his game. All the crowd could see when he was going to put a full-back into the Railway Stand."

Chesterfield

The following season, he joined his hometown club Chesterfield, with Martin Henderson and £8,000 going to Port Vale.^[16] Newton scored two goals on his debut on 15 October, in a 4–2 win over Rochdale.^[17] He spent two seasons at Saltergate and topped the Spireites' goalscoring chart in both seasons, forming a powerful front three with Phil Brown and Ernie Moss.^[16][13] After leaving Chesterfield Newton returned to Hartlepool in the summer of 1985 for a fee of £17,500 on the promise of better wages.^[6][18][16]

Later career

After his return to Hartlepool, Newton struggled with illness and injury and was limited to two goals in 11 league matches before being loaned to Stockport County and subsequently released.^[6] He finished his Football League career with the Bristol Rovers in 1987. He then played for the Cyprus-based AEP Paphos and Hong Kong's Eastern and Lai Sun, before returning to England.^[12] He later played for several non-League clubs, including Goole Town, Boston United, Alfreton Town and Oakham United.^[19][6]
