Milwaukee Brewers closer Eric Gagne was diagnosed Thursday with rotator cuff tendinitis and is sidelined indefinitely.
After being examined in Milwaukee by team physician William Raasch, Gagne received a cortisone injection and was told not to throw for three days. After that, Gagne will be re-examined and will not throw again until his shoulder feels better.
The Brewers don't plan to put him on the disabled list.
Gagne, taken out of the closer's role briefly this month because of ineffectiveness, was lifted during the ninth inning of the Brewers' 7-2 win in Pittsburgh on Tuesday with shoulder stiffness. He gave up Jason Bay's two-run homer, walked two and threw 26 pitches in his first appearance in a week.
A top baseball official will formulate a proposal for instant replay, and the technology could be tested in the Arizona Fall League this year.
