Southampton signings Paul Onuachu and Kamaldeen Sulemana are likely to miss today's clash with Brentford.
The pair had not received their work permits on Friday.
Saints boss Nathan Jones said, "We are uncertain because it is about their work permits.
"We will hopefully see them in the near future.
"They are in the building, but what we can do with them is limited due to the situation with the work permits."
