12:08pm: The Cardinals will send Rasmus, Trever Miller, Brian Tallet, and P.J. Walters to the Blue Jays for Jackson, Rzepczynski, Dotel, and Corey Patterson, tweets ESPN's Buster Olney. Olney adds that Miller is then expected to be traded to the White Sox.
12:01pm: This trade is not yet official because of the money involved, tweets Danny Knobler of CBS Sports. He says that aspect may need to be reworked before it's approved.
11:35am: A trade of Rasmus to the Blue Jays for Jackson, Dotel, and Rzepczynski is imminent, reports Joe Strauss of the St. Louis Post-Dispatch. He says an announcement could come early this afternoon.
11:22am: Edwin Jackson is definitely going to be traded by the Blue Jays, tweets SI's Jon Heyman. Heyman heard it's going to be for Cardinals outfielder Colby Rasmus. Rasmus being under team control through 2014 and still highly-regarded, the Cards will require more than just two months of Jackson. The two teams have talked about Marc Rzepczynski and Octavio Dotel, notes Olney, and Jon Paul Morosi of FOX Sports tweets that the Cards asked about outfielder Eric Thames.
Rasmus is a popular trade target. ESPN's Buster Olney tweets that the Rays offered one of Jeff Niemann, Wade Davis, and Alex Cobb, and the young center fielder is very much available. The Indians have interest as well.
