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.

The Chargers made Keenan Allen's return official on Wednesday and the wide receiver's return to Los Angeles means that another player's time on the roster has to come to an end.

The Chargers and Keenan Allen are officially reuniting. Los Angeles is signing Allen to a one-year, $8.5 million contract, NFL Network Insiders Ian Rapoport and Tom Pelissero reported. The team announced the deal shortly after.
