Millwall and Middlesbrough meet for a vital contest in the race for the Championship play-offs on Saturday afternoon (15:00 BST).
The Lions are three points behind seventh-placed Boro and five points off the top six after three wins from their past four games.
Boro have won five of their previous eight matches (D1 L2) and are two points behind Coventry City in sixth.
Millwall have lost both of their previous two league games against Middlesbrough, never before losing three in a row against them.
After their 1-0 win in December, Middlesbrough could complete their fourth league double over Millwall, after 1928-29, 1973-74, and 2014-15.
