A source tells Jeremy Fowler that Jerick McKinnon is returning to the Kansas City Chiefs.

The depth chart for the Kansas City Chiefs includes a starter, a veteran, and a draft pick.

While competing for carries with Gore andEdwards-Helaire, Darrel Williams signed with the ArizonaCardinals.

He was a free agent last year. He played mostly on special teams during the regular season but emerged on offense during the playoffs, when he led the team with 150 rushing yards and was third on the team with 14 receptions for 165 yards.

During his time with the Minnesota Vikings, he rushed for more than 500 yards three times.

He signed as a free agent with the San Francisco 49ers, but didn't play in the first two seasons because of a torn anterior cruciate ligament. He ran for 319 yards and caught 33 passes.
