EL SEGUNDO, Calif. (AP) — Keenan Allen walked into Los Angeles Charges training camp on Thursday feeling at home, despite a head coach and training facility that were new to him. The six-time Pro Bowl wide receiver got to work two days after signing with the team that drafted him in 2013 after spending last season with the Chicago Bears.

Los Angeles Chargers undrafted rookie quarterback DJ Uiagalelei had been wearing No. 13 through the first three weeks of training camp, including in the Hall of Fame Game last week. It never quite felt right.

McConkey was the primary slot receiver for the Chargers last season, but Allen could steal that job. It doesn't mean that McConkey can't win as an outside receiver, but Allen's presence lowers McConkey's ceiling.
