Rodriguez (back) is expected to join Triple-A Durham for a rehab assignment Sunday, Adam Berry of MLB.com reports.
Rodriguez has been on the injured list since Sept. 3 due to a lower-back strain. If all goes well on his assignment, the right-hander should return to Tampa Bay before the end of the season. He's unlikely to be a factor in fantasy leagues at this point but should bolster the playoff-bound Rays' bullpen during the postseason.
