Doubront will throw a bullpen session at some point this week.
The left-hander was shut down for a start because he has pitched 122 2/3 innings, which is just shy of his career high as a professional.
Prior to the All-Star break, Doubront went 9-4 with a 4.41 ERA. Since then, he is 1-2 with a 5.74 ERA.
