Boxingtalkers should not be surprised if HBO staple, undefeated welterweight contender Andre Berto's next three fights take place on Showtime. The move, according to sources close to the situation would come following HBO's uncertainty in scheduling him fights. BT also understands that Berto's first of three potential fights with Showtime in 2008 could take place in a special edition of ShoBox on February 29.  Both Berto and HBO VP Kery Davis was unavailable for immediate comment.
