Troy Renck of the Denver Post has the good news:
Rockies’ two-time all-star shortstop Troy Tulowitzki will begin a rehab assignment Wednesday in Triple-A Colorado Springs. He’s likely to play two-to-three games with Sky Sox, leaving him in position to join the Rockies over the weekend in Detroit or Tuesday for the opening of the series against the Phillies.
Tulowitzki has been on the disabled list since the final day of May with a strained left groin muscle.
The 27-year-old was batting .287/.360/.486 with eight home runs and 27 RBI in 47 games before the injury.
