Hot off the heels of Tiger Woods' announcement that he's taking an indefinite break from pro golf, PGA Tour Commissioner Tim Finchem is speaking out to ET. Plus, reactions from Tiger's sponsors AT&T and Nike!

"We fully support Tiger's decision to step away from competitive golf to focus on his family. His priorities are where they need to be, and we will continue to respect and honor his family's request for privacy," Finchem says in a statement.

"We look forward to Tiger's return to the PGA Tour when he determines the time is right for him."

Meanwhile, a rep for AT&T tells us: "We support Tiger's decision and our thoughts will be with him and his family. We are presently evaluating our ongoing relationship with him."

A rep for Nike tells ET: "Tiger has been part of Nike for more than a decade. He is the best golfer in the world and one of the greatest athletes of his era. We look forward to his return to golf. He and his family have Nike's full support."
