Romano (back) is scheduled to throw another bullpen session Wednesday, Arden Zwelling of Sportsnet.ca reports.
Romano resumed throwing off a mound over the weekend and has responded well so far. Out since late July due to lower-back inflammation, he could skip a minor-league rehab assignment and return to the Blue Jays' closer role when first eligible this Sunday. Erik Swanson and Jordan Hicks have largely been sharing ninth-inning duties in his absence.
