The team's poor start to the season has resulted in speculation about Redknapp's future at the club, while the board has had to step in this week after the boss accused Adel Taarabt of being three stone overweight.
As a result, Taarabt is unlikely to feature this weekend, with Redknapp believing that he is not fit, while Joey Barton and Jordan Mutch are expected to need a late fitness test after missing the last few games with hamstring injuries.
Meanwhile, Aston Villa will be keen to end a run of four straight defeats, a streak that has seen them slip to 12th in the table.
Philippe Senderos and Nathan Baker will both need late fitness tests ahead of the game, with Senderos still carrying a thigh problem that he picked up on international duty, while Baker was forced out at Goodison Park with a hamstring injury.
While Ron Vlaar and Christian Benteke have both recently returned from spells out injured, Lambert has confirmed that he is trying to ease them back to match fitness, so they could start on the bench.
When the sides last met in the 2012-13 season, Aston Villa claimed a home win, but were held to a 1-1 draw on their visit to Loftus Road.
