SAN DIEGO -- Chargers receiver Chris Chambers remained sidelined Thursday with a sprained ankle.
Chambers, who leads the Chargers with five touchdown catches, hasn't practiced since hurting his ankle in a loss at Miami on Oct. 5.
Chambers remains uncertain when he will return, but said he's experienced no setbacks during his rehabilitation.
"Not at all," said Chambers, who has 11 catches for 226 yards. "It's progressively getting better. I did more today, and every day it is getting better."
Whether his ankle heals in time for San Diego's game at Buffalo this weekend -- followed by a game in London against New Orleans -- remains to be seen.
"I definitely don't want to rush back. I have to be patient," he said. "But I definitely don't want to miss any more games, so we'll see. It will probably be a game-time deal."
The Chargers didn't miss Chambers in Sunday's 30-10 rout of New England. Vincent Jackson and Malcom Floyd -- Chambers' replacement -- combined for eight catches, two touchdowns and 209 receiving yards.
Before Sunday, Floyd had zero catches this season.
"I'm ecstatic ... very happy for him (Floyd) because he deserves it," Chambers aid. "He works just as hard as anybody on this team and he has a great ability that everybody could see."
Floyd is in his third season but has been slowed by injuries while working his way up San Diego's depth chart.
"Oh yeah, it's been a roller coaster," said Floyd. "But I have to just stay mentally tough, be ready at all times and be focused."
