Well this is somewhat unexpected.

After Friday's loss to the Dodgers the Cubs designated Julio Borbon for assignment.

Now we know who's going to replace Murphy on the 25-man (and 40-man) roster:

Murphy is an infielder. Borbon is an outfielder. This leaves just four outfielders on the Cubs' 25-man roster: Junior Lake Nate Schierholtz David DeJesus and Cole Gillespie. I can't imagine this situation will last too much longer -- not only that but the Cubs are still carrying eight relief pitchers. I'd guess Brian Bogusevic who is now eligible to return from the disabled list will be back soon.
