Career
2021
In round 5 of the 2021 NRL season, Crichton was fined $1350 by the NRL for pulling benched Canberra Raiders player Joseph Tapine into a celebratory throng and goading him.[14]
Critchton played a total of 26 games for Penrith in the 2021 NRL season including the club's 2021 NRL Grand Final victory over the South Sydney Rabbitohs. Crichton scored what would be the match winning try off an intercepted Cody Walker pass as Penrith held on to win 14–12.[15]
On 19 October, Crichton was handed a proposed $4000 fine by the NRL and a breach notice which alleges that he acted contrary to the best interests of the game after he was photographed on social media acting in a disrespectful manner toward the Provan-Summons Trophy. Although Crichton nor any of the Penrith players had broken the trophy, the NRL alleged Crichton and teammate Nathan Cleary showed disrespect towards the individuals depicted in the iconic moment on the trophy.[16]
2023
On 16 January, Crichton's management informed Penrith that he would be seeking other opportunities for 2024.[24] On 19 January, Fox League reported that Crichton signed with the Canterbury-Bankstown Bulldogs for four years starting in 2024, which was confirmed by the club on January 22.[25][26]
On 18 February, Crichton played in Penrith's 13–12 upset loss to St Helens RFC in the 2023 World Club Challenge.[27]
In round 8 of the 2023 NRL season, Crichton scored a hat-trick in Penrith's 20–18 loss against South Sydney.[28]
On 22 May, Crichton was selected by New South Wales in the extended squad for game one of the 2023 State of Origin series.[29]
During the 2023 NRL season, Crichton played 24 games for Penrith and emerged as the team's second-leading try-scorer.[30] With 15 tries for the season, he was one of the competition's highest-scoring centers.
Crichton was instrumental in the club's 26–24 victory over Brisbane in the 2023 NRL Grand Final as Penrith won their third straight premiership, successfully overturning a 24–8 deficit in the final 20 minutes. Crichton kicked the opening conversion of the grand final, in addition to scoring the second try of Penrith's comeback, breaking through three tacklers to emphatically slam the ball over the try line. In the final minutes of the match, Crichton managed two clutch kicks that both found out-of-position Broncos defenders and forced repeat sets. The second would prove decisive, capitalised upon by Nathan Cleary to score the match-winning try.[31] The grand final was Crichton's 100th and final match for the Panthers.
2024
On 22 February, Crichton was announced as the captain of the Canterbury-Bankstown Bulldogs.[32]
In round 1 of the 2024 NRL season, Crichton scored a try on debut for Canterbury as they were defeated 26–8 against arch-rivals Parramatta.[33]
On 26 May, Crichton was named at centre for New South Wales ahead of the 2024 State of Origin series.[34]

2025
In May, Crichton was selected by New South Wales ahead of game one in the 2025 State of Origin series. He played in all three games as New South Wales lost the series 2-1.[39]
Following an MCL injury to Canterbury teammate Matt Burton in a 40-24 round 2 victory against the Gold Coast Titans, Crichton took over as Canterbury's primary goalkicker. Crichton was pivotal in Canterbury's biggest comeback since 2001, as coach Cameron Ciraldo described his performance in the 32-20 away win against the Canberra Raiders as "putting the team on his back and turning nothing into something".[40]
In Canterbury's visit to Melbourne in round 25, Crichton was denied what would have been a match-levelling try as he failed to re-grip the ball before grounding. This controversial moment sparked debate amongst NRL legends such as Andrew Johns, who believed the rule was unfair, stating "That should be a try. Tell me how are you suppose to re-grip the ball? It's impossible."[41]
Crichton captained the Canterbury outfit to their first win against the Penrith Panthers since 2019 in round 26, with a 28-4 victory. Penrith controversially rested 16 of the players who played the previous week in a bid to prepare for the finals. This victory means that Crichton has now recorded victories against all of the 17 current NRL sides, having lost his first two encounters with his old club.
