Chavis (shoulder) started at first base and went 0-for-3 for Triple-A Pawtucket on Friday.
Chavis kicked off his rehab assignment Friday and will remain with the PawSox through the weekend, per Ian Browne of MLB.com. There's a chance he could join the Red Sox in Colorado on Tuesday for their upcoming series with the Rockies. Chavis has been sidelined with a sprained AC joint in his left shoulder since Aug. 12.
