Chargers' Merriman returns to practice

IRVING, Texas -- Chargers outside linebacker Shawne Merriman, who missed last week's game at Cleveland with a foot injury, returned to practice but was limited.

The other outside linebacker, Shaun Phillips, did not practice because of an ankle injury.

Defensive end Luis Castillo did practice fully as his calf injury seems to be healing. Guard Kris Dielman did not practice due to a non-football related injury.
