QB Trevor Siemian (bruised left shoulder) returned to practice Thursday.

“I think we took a big step forward today,” Kubiak said, adding that however Siemian feels Friday will go a long way toward determining whether he’ll start over Paxton Lynch this weekend.

Siemian — who was named the AFC’s Offensive Player of the Week in Week 3 — left Sunday’s game against Tampa Bay late in the second quarter after a sack by Clinton McDonald. He sat out practice on Wednesday.
