Khan vs Peterson Weigh-In Photos: Khan 139, Peterson 140, Plus Undercard Weights

Amir Khan weighed in at 139 pounds for his Saturday night WBA and IBF junior welterweight title defense against Lamont Peterson in Washington, DC, with Peterson coming in at 140 pounds on the nose.

Both fighters look to be in good shape, and whatever you expect of the HBO main event on tomorrow night, it doesn't look as though conditioning will be a factor in the fight not meeting expectations.

In the heavyweight HBO-televised co-feature, Seth "Mayhem" Mitchell came in at 240½, while 36-year-old Timur Ibragimov weighed in at 221, his lowest trip to the scales since 2006, though not notably lower. Ibragimov has generally weighed in the low 220s, while Mitchell hit right around the mark he said he prefers.
