Gaines (knee) will be the starting right cornerback in Sunday's matchup with the Chargers, BJ Kissel of Chiefs.com reports.

Analysis:

The 25-year-old is entering his third year in the league. His sophomore season was cut short after just three games due to a torn ACL. He returned to action in Week 3 of the preseason before sitting out the final game along with several other starters. He was expected to assume the starting right cornerback role if he could avoid any setbacks, which has indeed been the case.
