Callum Tyler Whelan (born 24 September 1998) is an English professional footballer who plays as a midfielder for EFL League Two club Carlisle United.
[7] He failed to make it into a match-day squad under new manager John Askey, who felt he was not yet ready for senior football, and the loan was ended early on 2 April.
[9][10] He made his first-team debut for Watford in the fourth round of the FA Cup on 4 January 2020, coming on as a 61st-minute substitute for Domingos Quina in a 3–3 draw with Tranmere Rovers at Vicarage Road.
[18] On 26 July 2022, Whelan signed a one-year contract with National League club Solihull Moors after a trial period, during which he scored a goal in a friendly against Brackley Town.
[19] He played 20 matches for the club, but lost his first-team place due to injury and increased competition in the midfield, so in February 2023 he moved on loan to league rivals Gateshead until the end of the 2022–23 season.
[28] On 3 January 2025, Whelan signed for League Two side Carlisle United on a two-and-a-half year deal for an undisclosed fee, reuniting with head coach Mike Williamson whom had first brought him to Gateshead.
