The San Diego Chargers placed wide receiver Malcom Floyd and outside linebacker Dwight Freeney on season-ending injured reserve.
Floyd's agent, Buddy Baker, wrote on Twitter on Tuesday that his client "will be back &stronger than ever next season" following the next injury he suffered in Week 2.
Floyd was injured during San Diego's victory in Philadelphia and was carted off the field, but Fox Sports' Mike Garafolo reported Floyd will not require surgery and could play in 2014.
Freeney, signed in the offseason from Indianapolis, suffered a torn quadriceps against Dallas last Sunday.
The Chargers signed free agent wide receiver Lavelle Hawkins on Tuesday. Hawkins spent five years with the Tennessee Titans and spent time with the Patriots and 49ers over the offseason. He caught four passes for 62 yards and a touchdown against San Diego during the preseason.
The team also promoted outside linebacker Thomas Keiser from the practice squad and replaced him with offensive tackle Andrew Tiller.
