William Gallas is fit to face West Ham in Saturday's big derby in the Premier League at the Lane.
There were fears that the defender had picked up a fresh hamstring injury in training earlier the week but, thankfully, scans proved otherwise and he trained on Friday.
"William joined in (training) and he was fine," reported Harry after training. "He limped off on Tuesday morning, but he was fine.
"He gets over injuries quickly, William, plays through little niggles and he felt okay."
There was more good news as Tom Huddlestone returned to full training for the first time since November after recovering from an ankle injury.
"Tom trained for the first time today and looked like he'd never been away," added Harry.
"He has two weeks now where we can really work him and hopefully he'll then be back and ready to play."
Wilson Palacios (knee), Ledley King (groin), Younes Kaboul (knee) and Jonathan Woodgate (groin) remain out this weekend.
