Michael Paul Trevor Bostwick (born 17 May 1988) is an English professional footballer who plays as a defender for National League club Boston United.

At the age of 17, he joined Conference National club Crawley Town on a work experience loan during the latter stages of 2005–06 season.

Bostwick rejected a contract offer from Ebbsfleet, and signed for Stevenage Borough shortly after the FA Trophy success.

[7] During the latter stages of the 2005–06 season, Bostwick joined Conference National club Crawley Town on work experience.

[8] He made his debut for Crawley a week after joining the club, coming on as an 89th-minute substitute in a 1–0 victory against Forest Green Rovers on 18 March 2006.

[14] Crawley Town extended the loan deal until the end of the season on 31 August 2006, although Millwall were able to recall him in the January transfer window if they deemed it necessary.

[16] Having made no first-team appearances for Millwall, Bostwick was allowed to leave the club on a free transfer to sign for Rushden & Diamonds on an 18-month contract.

[19] He was sent-off for the first time in his career in Rushden's 2–2 draw with Aldershot Town on 24 March 2007, receiving a red card for two bookable offences.

[23] He made his Ebbsfleet debut on 18 August 2007, starting the match at centre back in a 1–0 victory at Nene Park against his former employers, Rushden.

[30] He made his debut for Stevenage in the club's opening match of the season, a 5–0 defeat to Wrexham at the Racecourse Ground on 9 August 2008.

[31] Bostwick was used in both the centre of defence and central midfield during the first half of the 2008–09 season, as well as playing at full back in the club's 1–0 defeat to Kettering Town in September 2008.

[37] Bostwick's first goal of the 2009–10 season came in the club's 2–1 victory against Rushden & Diamonds at Broadhall Way on 29 August 2009, scoring from the edge of the area to give Stevenage the lead.

[56] Bostwick played regularly during the 2011–12 season, making 53 appearances and scoring eight goals from midfield,[57] as Stevenage lost 1–0 over two legs in the League One play-off semi-final.

[61][62] Peterborough chairman Darragh MacAnthony stated that Bostwick was manager Darren Ferguson's "number one transfer target for the summer".

[64] Bostwick scored his first goal for the club in his fourth appearance, halving the deficit with a "stunning volley from the edge of the area" as Peterborough lost 2–1 at home to Leeds United on 25 August 2012.

[72] This included six appearances in the Football League Trophy as Peterborough won the competition; Bostwick played the whole match in the final, a 3–1 victory against Chesterfield at Wembley Stadium on 30 March 2014.

[72][73] He signed a new three-and-a-half-year contract with Peterborough on 10 March 2015, with MacAnthony stating Bostwick could return to his midfield role as "you can see what he brings to that position".

[80] He joined Lincoln for an undisclosed fee, with Peterborough having received a higher offer from Blackburn Rovers, although Bostwick did not want to relocate to the north of England.

[81] He made his debut for Lincoln in the club's 2–2 draw away at Wycombe Wanderers on 5 August 2017,[82] and scored his first goal in a 2–1 victory against Chesterfield at Sincil Bank on 7 October 2017.

[83] During the 2018–19 season, Bostwick scored in Lincoln's FA Cup third round 2–1 defeat to Premier League club Everton on 5 January 2019.

[86] Having started the 2019–20 season as a regular in the first-team line-up, Bostwick sustained a calf injury in Lincoln's 1–0 home defeat to Bristol Rovers on 14 September 2019, during which he was a substituted at half-time.

[91] The transfer materialised after Bostwick had spoken to his former teammate and Burton fitness coach Chris Beardsley about joining the club.

[92][96] Described as "influential" and "key" during the second half of the season,[93][97] Burton confirmed that Bostwick had signed a one-year contract extension with the club in July 2021.
