Montgomery (COVID-19) is expected to return from the injured list to start one game of Tuesday's doubleheader against the Red Sox, Lindsey Adler of The Athletic reports.

The left-hander rejoined the team this weekend after testing positive for COVID-19 on Aug. 3, and he's poised to re-enter the starting rotation Tuesday. Montgomery has a 2.22 ERA, 0.99 WHIP and 29:9 K:BB over his past five starts (28.1 innings), and he'll attempt to pick up where he left off before he tested positive for the virus.
