Middlesbrough manager Tony Mowbray remains hopeful Rhys Williams will play again this season despite suffering an ankle ligament injury.
The 23-year-old midfielder missed Saturday's with the problem, with no time scale placed on his return.
"He's damaged ligaments in his ankle, so it's never a week or so," Mowbray told BBC Tees.
"Let's hope we can see him again this season and he's got a part to play."
Mowbray added: "He'll have two or three weeks in a cast, and then we'll reassess once he has that off and starts running to see how bad it is."
Williams, an Australia international, has been a regular for Middlesbrough this season with 39 appearances and recently signed a four-year deal at the Riverside.
