This is from Rafael off ESPN -
"We have a ruling from Showtime: Glen Johnson wins scorecard tiebreaker over Abraham so semis are: No. 1 Ward-4 Abraham & 2 Froch-3 Johnson."
The article you linked was from June 2010, in the year since he has fought at welter. Also, if we're being pedantic, you said he didn't fight at '147'. Amateur welter is 152.
