The Braves have not announced who will start Tuesday vs. the Giants in place of Hanson, who is experiencing right shoulder discomfort for the second time this season. An MRI exam performed last week indicated that he is once again dealing with tendinitis -- the same problem he was diagnosed with when he was placed on the disabled list in June.
Hanson returned from the disabled list in late June and made three strong starts before the All-Star break. However, he has posted an 8.10 ERA in his five starts since the break.
The Braves also announced right-handed reliever Scott Linebrink has been activated from the disabled list and right-handed reliever Anthony Varvaro has been optioned to Triple-A Gwinnett.
