Martin Truex Jr. is planning to retire at the end of the 2024 NASCAR Cup Series season, The Athletic reported Thursday.

Truex, 43, is expected to announce his retirement Friday at his pre-race news conference at Iowa Speedway ahead of this weekend’s Iowa Corn 350.

Truex was the 2017 NASCAR Cup Series champion and a two-time regular-season champion (2017, 2023). He finished the series in second place in 2018, 2019 and 2021 and faded to an 11th-place finish last season after his stellar regular season.

Truex has won 34 Cup Series races, most recently at New Hampshire Motor Speedway in 2023. He also won the NASCAR Xfinity Series title in 2004 and 2005.

Chase Briscoe is a leading candidate to take Truex’s spot in the Joe Gibbs Racing lineup, The Athletic reported. Briscoe, 29, is in need of a new home in 2025 when his current team, Stewart-Haas, closes up shop at the end of the current campaign.
