Broncos top tackler Brandon Marshall says he expects to play Sunday night at Kansas City after clearing concussion protocol and practicing in full Friday.

Marshall was knocked out of last week's win over the Dolphins when he ran into 6-foot-4, 265-pound tight end Dion Simms on T.J. Ward's interception return.

Simms was unfazed while Marshall was wobbly and walked off the field with assistance.

Marshall says he was confident he'd clear the league's concussion protocol this week.

This was the first concussion of Marshall's career.

Marshall is officially listed as probable. Aqib Talib (hamstring) is 50-50. Three players are out: Kayvon Webster (shoulder), Ronnie Hillman (foot) and Montee Ball (groin).
