Rock Kubatko of MASN Sports reports Markakis is "likely" to have the surgery and heard it is "probably going to happen in two weeks."
The surgery, which would be to repair a herniated disc in his cervical spine, carries up to 12 weeks of recovery time, according to Rosenthal.
Kubatko reports that because of Markakis' condition, the Orioles were hesitant to offer the 31-year-old a guaranteed fourth year. The Braves reportedly conducted an independent evaluation of the outfielder and felt comfortable offering their deal.
In 155 games this year, Markakis hit .276 with 14 home runs, 50 RBI and a .342 on-base percentage. Markakis has a career .290 average and .358 on-base percentage with 141 home runs and 658 RBI.
