– I do not know if you heard but Brett Favre has un-retired. And he will be playing this season in New York for the Jets. Sorry ESPN, his first game back will be on the NFL Network on Saturday at 8 p.m. EST. Maybe Rachel Nichols can give updates from the sidelines on Favre’s progress in grasping the Jets offense for ESPN News.

– The men’s 100-meter finals in track & field take place on Saturday evening. It could be the most competitive event at the Olympics, as all of the contenders have beaten one another in the past. Asafa Powell of Jamaica was defeated by USA’s Tyson Gay at the World Championships so badly that he disappeared from the scene. His countryman, Usain Bolt, returned the favor by beating Gay this past May. All three will run in Beijing, and it might just be the best 10 seconds of the Olympiad.

– Michael Phelps is on target to break Mark Spitz’s record of seven gold medals at one Olympic competition. The 100-meter butterfly is this evening, with the 4 x 100 medley relay wrapping up the swimming competition (and Phelps’ quest) on Saturday night.

– The top matchup in baseball this weekend could be a possible playoff preview between the Milwaukee Brewers and Los Angeles Dodgers at Chavez Ravine. Both teams made significant additions to improve their chances of playing into October, so this should be a good series.
