Defending champion Charl Schwartzel will have Keegan Bradley in his group when the 76th Masters gets underway Thursday at Augusta National Golf Club, while three-time winner Phil Mickelson will play alongside Hunter Mahan.

However, Dustin Johnson will not be taking place after withdrawing due to an injury.

Schwartzel won last year's title by two strokes over Adam Scott and Jason Day, earning his first major victory. His trio, which includes reigning PGA Championship winner Bradley and U.S. Amateur champion Kelly Kraft, will tee off at 10:24 a.m. (ET) on Thursday and 1:31 p.m. on Friday.

Immediately after Schwartzel's group will be a trio including Tiger Woods, a four-time Masters champion. He last won at Augusta in 2005, but has finished in the top six every year since.

Woods, who won two weeks ago at the Arnold Palmer Invitational, will begin his quest for a fifth title at 10:35 a.m. on Thursday with Miguel Angel Jimenez and Korean Sang-Moon Bae, a first-time participant. That trio will come back at 1:42 p.m. on Friday.

Mickelson will be searching for his fourth Masters title, having won in 2004, 2006 and 2010. He will be playing alongside Mahan, who won the Houston Open this past weekend and became the highest-ranked American in the world, at No. 4. That group, which includes Swede Peter Hanson, has the final tee time Thursday at 1:53 p.m. The trio tees off at 10:46 a.m. on Friday.
