ENGLEWOOD, Colo. — Cornerback Pat Surtain II returned to practice Thursday and is expected to play in Saturday's preseason game in Seattle.

Surtain, who missed most of Tuesday's practice and all of Wednesday's session with a lower-leg injury, was on the field for Thursday's walkthrough-style practice.

"I think so," Fangio said when asked if Surtain could play vs. the Seahawks. "We're going to wait and see how he feels after today and tomorrow. But I think he will. But if there's anything there, we'll take the conservative route."

Running back Melvin Gordon III, who returned to practice this week after dealing with a groin injury, may also be healthy enough to play in Seattle.

"He could play," Fangio said. "We'll see how he feels … with his little issue that he has. We'll make that decision come Saturday."

Outside linebacker Malik Reed also returned to practice Thursday after missing Wednesday's session with an ankle injury. Safety Kareem Jackson also practiced after a presumed vet day on Wednesday.

Running back Mike Boone (quad), safety Trey Marshall (ankle) and outside linebacker Andre Mintze (concussion) were the only players not to practice.

Fangio said Boone's rehab is "coming along as expected" but that he expected Boone to miss three to four weeks from when he suffered his injury on Aug. 12.
