Jason Puncheon and Calvin Andrew will be added to the Millwall squad for the trip to Middlesbrough.
Southampton winger Puncheon and Crystal Palace striker Andrew have this week been drafted in on loan until January after the Lions were hit by a spate of injuries.
Wideman Chris Hackett is out for a fortnight with a hip injury picked up against Sheffield United last weekend and forwards Kevin Lisbie and Theo Robinson are sidelined by knee problems.
Boss Kenny Jackett will also have to do without versatile defender Scott Barron, who has been an ever-present this term but must serve a one-match ban after collecting a fifth booking against the Blades.
Tony Craig is Barron's likely replacement at left-back.
