ENGLEWOOD, Colo. (AP) The Denver Broncos face critical decisions two weeks before the Super Bowl champions open the season.

They have more questions than answers heading into the third preseason game, none more glaring than at quarterback. Trevor Siemian was named the starter ahead of veteran Mark Sanchez for the game against the Los Angeles Rams on Saturday.

The offensive line is still unsettled, most notably right guard. Ty Sambrailo was the projected starter but a hyperextended elbow has sidelined him for most of training camp. Darrion Weems was playing well in place of Sambrailo but suffered a concussion against San Francisco.

C.J. Anderson is the clear No. 1 running back but veteran Ronnie Hillman's spot on the roster is in jeopardy because of the play of rookie Devontae Booker and second-year back Kapri Bibbs.
