Chargers Injury List: Mathews, VJ, M80 and SP95 Not Practicing

Mike Tolbert and Antonio Gates are out and practicing today. Tolbert was not able to play against the Chiefs and it looks like he should be available and might be the starter against the Pack.
Gates played a lot of snaps on Monday and it is definitely a good sign that his foot is doing well.
Ryan Mathews, Curtis Brinkley, Vincent Jackson, Malcom Floyd, Kris Dielman and Shaun Phillips are not out on the practice field. Same story as always with our receivers all sitting sideline for practice. Who is Philip throwing to at practice?
Now we have a pair of running backs sitting sideline with them and they might not be available on Sunday. Dielman will take another week off with his concussion.
Wondering how bad SP95’s injury is. He missed out all last week and we just recently signed Everette Brown for help at outside linebacker. Sure doesn’t sound good.
With all our injuries, how do you practice to get better?
