The Dodgers reinstated reliever Ronald Belisario from the Restricted List on Thursday after the right-hander finished serving a 25-game suspension for failing to comply with baseball's drug policy.
Belisario will be eligible to pitch when the Dodgers begin a three-game series against the Chicago Cubs on Friday at Wrigley Field.
In February, Belisario, who is from Venezuela, admitted he had tested positive for cocaine and that had prevented him from obtaining the neccessary paperwork for a visa to enter the United States, and also forced him to sit out all of last season.
To open a roster spot for Belisario, the Dodgers also announced they had desinated right-hander Mike MacDougal for assignment.
Belisario previously said he does not have a problem with any drugs and that his positive cocaine test was the result of "a one-time thing."
During his 25-game suspension, Belisario, 29, made four appearances for Triple-A Albuqueque and Single-A Rancho Cucamonga.
Belisario was a key member of the Dodgers' bullpen as a rookie in 2009, posting a 2.04 ERA in 69 appearances, before that figure ballooned to 5.04 in 59 games in 2010.
MacDougal, 35, posted a 7.94 ERA in seven appearances this season.
