Davis requested a trade earlier this offseason, NFL.com's Ian Rapoport reports.
The Chiefs appear set at running back after Spencer Ware and Charcandrick West filled in capably for Jamaal Charles (torn ACL), who says he's ahead of schedule in his recovery. With Ware and West both agreeing to extensions Thursday, the Chiefs have all three running backs under contract through at least 2017, leaving Davis as the odd man out. Despite running a 4.37 40-yard dash at 227 pounds at the 2012 Scouting Combine, the 24-year-old Davis has averaged just 3.3 yards on 232 carries through three seasons. He won't fetch anything more than a late-round pick, and the Chiefs may ultimately just end up releasing him. If he does stick in Kansas City, it will likely be due to his strong track record as a kickoff return man.
