SAN DIEGO -- Every-down running back Ryan Mathews, inside linebacker Manti Te'o, safety Jahleel Addae, and outside linebackers Jeremiah Attaochu and Melvin Ingram are all expected to return from various injuries and practice this week.

Having those playmakers back should give the San Diego Chargers, losers of three straight, a boost on both sides of the ball. But don’t tell that to Chargers head coach Mike McCoy, who said the rest of the team has to play better in order for those injured players to have an impact on Sunday against the Oakland Raiders.

“Ryan Mathews does not guarantee us 200 yards rushing,” McCoy said. “It’s the other 10 guys on the field that have to do their jobs better. We’ve talked about that as a football team. We ran the ball fairly well with No. 43 (Branden Oliver) back there plenty of times. We won five games without these guys.

“So it’s a matter of everyone playing better. And it’s not just a couple guys coming back that’s going to make it so all of a sudden you’re winning a football game. All 46 players have to play better. We have to coach better.”

That said, receiver Eddie Royal acknowledged the return of Mathews could bring more of a physical presence to San Diego’s offense. Mathews has been out since Week 2 with an MCL knee sprain but practiced last week.

“He runs physical,” Royal said. “He’s fast also, so he can make that long run. It’s just brings a physical nature to our team, having that guy in the backfield that guys don’t want to come up and tackle. It adds another dynamic to our offense.”

Ingram, placed on injured reserve designated to return on Sept. 20 with a hip injury, is eligible to return to practice this week after missing seven games and could play against the Raiders on Sunday.

Te’o suffered a fractured foot against Buffalo in Week 3 and has not practiced since. Attaochu missed five games with a hamstring injury. Addae missed the Miami game while recovering from concussion-like symptoms.

McCoy said players had meetings and went through a light walk-through Monday. McCoy said he’ll give players the day off on Tuesday, and the Chargers will get back on a regular schedule with a Wednesday practice.
