According to Morosi, the Tigers have moved Porcellos latest Triple-A Toledo start back a day, with sources saying it may be to allow Porcello to throw in front of numerous scouts from other major league teams.

Morosi reports the Tigers would likely only trade Porcello, who is 4-7 with a 6.14 ERA this year, in exchange for another pitcher who would be in Detroit long-term.  One name that Detroit can cross off its list is Houstons Roy Oswalt, who reportedly refuses to waive his no-trade clause to come to the Tigers.
