Evening AFC West notes

San Diego offensive linemen Johnnie Troutman and Brandyn Dombrowski are returning to practice from the physically unable to perform list. The team has a three-week window to either add them to the active roster or place them on injured reserve.

Cornerback Stanford Routt, as expected, cleared waivers Tuesday after the Chiefs cut him on Monday. Routt, in the first year of lucrative three-year deal, was expected to clear waivers because of that big contract. He should get interest as a free agent.

The NFL is continuing the investigation that stemmed from the Chargers using sticky towels against Denver in Week 6.
