Patterson Will Defend Title Against London

INDIANAPOLIS, April 30--Floyd Patterson will defend his world heavyweight boxing title tomorrow against England's Brian London, a sturdy "tuneup" foe for the champion's June date with Ingemar Johannsson. The match will take place here at 9 p.m. EST.

London, a lantern-jawed former British champ with over 20 pounds weight advantage, is regarded so lightly that odds against him have been quoted at 10 to 1.
