Galvao: 'Macaco' First, Then Diaz for the Title

A last-minute opponent switch-up hasn't fazed Andre Galvao at all, judging from this Sherdog.com video exclusive.

The Abu Dhabi Submission Grappling runner-up looks at his welterweight bout against Jorge "Macaco" Patino at Strikeforce "Houston" on Saturday as a major stepping stone toward title contention -- even though it will only be his sixth career fight.

Fans can decide on Saturday if Galvao, who fights under the Team Nogueira banner, is ready for Strikeforce welterweight champion Nick Diaz, as the preliminary bout will be one of two to air live and free on Sherdog.com starting at 9 p.m. ET.

Strikeforce "Houston" airs on Showtime at 10 p.m. ET/PT.
