Porte did not finish "La Doyenne" when he started in either 2013 and 2014.
"I've only lined up twice before so I'm not going in with any real expectations.
"I'm coming in off the back of altitude camp and my last block of stage races, so Liège-Bastogne-Liège will be a good chance to test the legs on these climbs," Porte said.
Samuel Sanchez who finished sixth at La Fleche Wallone on Wednesday is another option for BMC. Sanchez played down his chances in the fourth monument on the calendar.
"Liège-Bastogne-Liège is going to be really tough. We're looking at six or more hours in the saddle and it looks like the conditions will be really bad, so we'll have to see on the day," Sánchez said.
BMC for Liège-Bastogne-Liège: Joey Rosskopf, Alessandro De Marchi, Silvan Dillier, Ben Hermans, Richie Porte, Samuel Sánchez, Dylan Teuns, Loïc Vliegen
