Major League Baseball announced today that it has approved a roster substitution for the Atlanta Braves due to an injury sustained by pitcher Chris Martin. As a result, Martin will be replaced by right-handed pitcher Julio Teheran on Atlanta’s Division Series roster.

Dr. Gary Green, MLB’s Medical Director, confirmed the injury after communicating with the evaluating physician, as well as reviewing Martin’s medical history.

MLB Postseason rules provide that a Club may request permission from the Commissioner’s Office to replace a player who is unable to play because of an injury. The Commissioner’s Office may approve or disapprove the request based on the specific facts and circumstances. In accordance with the rules, Martin will be ineligible to return in the National League Championship Series if the Braves participate, but would be eligible to return for the World Series if Atlanta advances.
