The All-Pro has started 85 straight games and has played through toe injuries. The Chargers play host to the the New England Patriots on Sunday.
"My streak is on the line," Gates told the San Diego Union-Tribune. "More important is we're trying to make a run, make a push. The next few games are important to our season. I want to do whatever I can to help and not hurt the team."
Cornerback Kyle Arrington (groin) and wide receiver Julian Edelman (concussion) are listed as questionable for the Patriots.
Running back Fred Taylor (toe) and safety Jarrad Page (calf) will not play.
