Indianapolis Colts quarterback Anthony Richardson made a surprise appearance at the team's voluntary offseason workouts on Monday, according to a person familiar with the situation who spoke to The Associated Press on condition of anonymity.

The 23-year-old signal-caller had been training in his hometown of Jacksonville, Florida, while his agent explored potential trade options. His decision to rejoin the team marks the latest chapter in a rollercoaster four-year NFL career that began with immense promise.

Selected with the No. 4 overall pick in the 2023 NFL Draft, Richardson was viewed as the franchise quarterback the Colts had been searching for since Andrew Luck's sudden retirement in August 2019. The position had become a revolving door, with seven different starters in seven seasons before Richardson arrived.

His rookie campaign started with a bang, as he beat out veteran Gardner Minshew II for the starting job. But injuries quickly derailed the momentum. Richardson started just four games that season, completing only two of them before a season-ending shoulder injury to his throwing arm.

The 2024 season brought more struggles. Richardson completed just 47.7% of his passes – the lowest among regular starters across the league. He missed two games with an oblique injury and the final two contests with a back issue. However, the most defining moment came in October against the Houston Texans, when he took himself out of the game, later admitting he was exhausted. Head coach Shane Steichen responded by benching him for the next two games.

Determined to create competition, general manager Chris Ballard signed former New York Giants first-round pick Daniel Jones this offseason. Jones, the No. 6 overall selection in 2019, has also battled injuries and inconsistency throughout his career.

For now, Richardson's return to voluntary workouts signals a willingness to compete, but the Colts' quarterback room remains one of the most intriguing storylines heading into training camp.
