Chargers place 3 on injured reserve to trim roster to 75; Te'o out of walking boot

The San Diego Chargers have placed wide receiver Dan DePalma, fullback Chris Gronkowski and wide receiver Mike Willie on injured reserve to reach the roster limit of 75.

DePalma and Willie were hurt in Saturday night's exhibition victory against Arizona. Gronkowski had been out with an ankle injury.

Also Tuesday, Manti Te'o was out of the walking boot that has protected his sprained right foot since he was injured in the exhibition opener Aug. 8. Te'o did not practice, and coach Mike McCoy says the rookie linebacker was "just kind of really getting a good feel without the boot."

McCoy says he's not sure if Te'o will shed the boot for good, but hopes Te'o can be ready to start in the Sept. 9 opener against Houston.
