Full-back Kyle Walker-Peters has this week resumed training following a brief spell on the sidelines, and is likely to be available for this weekend's trip to the capital.
The manager confirmed that the Tottenham loanee has been involved in regular training over the past few days, and can be an option for Saturday's West Ham game, while Nathan Redmond will definitely miss out.
The forward suffered a muscle injury at Staplewood last week, and is predicted to be out for the next month, with an anticipated return date of the week following the March international break.
"So far it looks good," Hasenhüttl revealed, when asked about his squad selection. "Reddie is still out, so it will take maybe a little longer. But Walker-Peters is back in training.
"He's trained well this week. That's one more option we have.
"Redmond will take time, I think about one month. Hopefully not longer. Maybe after the international break he can play again, that is the schedule at the moment."
