Javontee Herndon

Javontee Herndon was in the mix to end this preseason as the Chargers' fifth wide receiver.

Unfortunately, that bid never began.

The receiver-returner injured his knee on July 30, the first day of training camp, while participating in what should've been a rudimentary punt return drill. Instead, he suffered a non-contact knee injury that required arthroscopic surgery last week, sources said. Herndon was waived-injured Tuesday, part of a cluster of roster moves the Chargers made when cutting from a 90- to 75-man roster by the NFL's 1 p.m. PT deadline.

Herndon will default to injured reserve upon clearing waivers Wednesday.
