Johnson, 31, was released by the Blue Jays on Sunday, and is expected to clear waivers because it is doubtful that any team will choose to assume his $3.275 million salary. Once he clears waivers, Johnson will be free to negotiate with any club.
The Red Sox, Rays and Rangers are among the other teams interested in Johnson, sources say, but the Cubs have been the most persistent suitor in early discussions.
