Maybe, depending on whether they got insurance and what kind.
From what I could find online, he didn't technically retire. He was not medically cleared to play. During the off season he had to be on the 40 man, then when the season starts, transferred to the 60 day injury list. The Tigers were responsible for $6M each year, the Rangers for $18M. The Rangers got insurance that covered half of their end.
That would be a nice break for the Tigers.
