Chicago Cubs closer Brandon Morrow is going back on the 10-day disabled list, this time with right biceps inflammation.
The move is retroactive to Monday. Chicago kicks off MLB's second half of the season against the Cardinals Thursday night (ESPN, 7 p.m. ET).
Morrow spent time on the disabled list a month ago when he suffered back spasms while undressing. Morrow has battled injuries throughout his career.
Anthony Bass was activated to take his place on the roster.
Morrow was signed in the offseason after he played one season with the Dodgers and dominated the Cubs in the postseason.
