Lawrie is expected to need approximately two weeks of Minor League games before rejoining the Blue Jays. The work will start in Dunedin, then eventually include a promotion to Triple-A Buffalo.
The news comes just one day after Blue Jays manager John Gibbons said that Lawrie was likely still two weeks away from a rehab assignment. He misspoke at the time, and general manager Alex Anthopoulos stated later that night the rehab was set to begin Wednesday.
Lawrie hit just .209 with 11 extra-base hits in 37 games for the Blue Jays this year. The prolonged offensive struggles came as somewhat of a surprise, but he still provided well-above average defense at third base.
The 23-year-old is a career .266 hitter with 25 homers and 87 RBIs in 205 games at the big league level.
