Manager Fredi Gonzalez told Teheran on Saturday he'll start on March 31 in Milwaukee. The Braves didn't have much choice after a string of injuries this spring.
Kris Medlen and Brandon Beachy are sidelined because of elbow ligament transplant surgery. Ervin Santana, who signed late as a free agent, and Mike Minor (shoulder) won't be ready to join the rotation until mid-April.
The Braves will go with three other starters the first two weeks of the season - Alex Wood, Freddy Garcia and rookie David Hale.
Teheran has a 1.42 ERA in five spring starts. He has 17 strikeouts and three walks while holding opponents to a .194 average.
