PORTLAND, Ore. (AP) - If Portland State coach Nigel Burton knows who his starting quarterback is, he isn't saying.

While most of the other Big Sky Conference teams appear settled at quarterback, and even the Pac-12's Oregon Ducks to the south finally named their starter on Friday, Burton is remaining mum about his choice until right before Saturday's opener against Montana's Carroll College.

Burton jokes - kind of - that he'll unveil his QB at 5:04 p.m. The game starts at 5:05 p.m.

The candidates include a pair of true freshmen, Kieran McDonagh and Paris Penn. The two newcomers have done so well that they're serious competition for junior quarterback Collin Ramirez and sophomore Josh Milhollin.

Another hopeful, speedy redshirt freshman Thomas Carter, has been moved to slot wide receiver.
