Woods announced last month that he intended to return to competition at Safeway, but he did not officially commit to the tournament until Friday. It will mark Woods' first competitive appearance since the 2015 Wyndham Championship, an absence of nearly 14 months as he recovered from multiple back surgeries.
While the early-round groupings will not be officially released by the PGA Tour until Tuesday, Mickelson had lobbied for the two to play together once Woods indicated his intention to tee it up at Silverado Resort & Spa.
"I'm hoping we can get paired together. That would be really fun. I would love it," Mickelson said last month. "It's great to have him back, and hopefully he's physically able to practice the way he needs."
Woods and Mickelson have not been paired together since the first two rounds of the 2014 PGA Championship at Valhalla, when Woods shot 74-74 to miss the cut and Mickelson shot 67-69 en route to a runner-up finish.
