Defender Ryan Dickson remains a doubt for Brentford's clash with Tranmere.

The 23-year-old missed the 2-1 defeat to Walsall last weekend with a knee injury, although the postponement of Tuesday night's visit to Colchester has allowed Dickson extra time to recover and he may yet feature.

Midfielder Marcus Bean was an unused substitute against Walsall after recovering from a knee injury and he will be hoping for a return to the starting line-up.

Lionel Ainsworth is still awaiting his full debut since joining on loan from League One rivals Huddersfield.

The winger has made three substitute appearances for the Bees and will push Sam Saunders for a starting berth.

Goalkeeper Nikki Bull remains sidelined with a shoulder injury.

Tranmere boss Les Parry will be without midfielder Gareth Edds.

The Sydney-born utility player suffered concussion in Tuesday's 2-0 home defeat at the hands of Huddersfield and was substituted at half-time.

He was replaced by Charlie Barnett, who will now compete with Alan Mahon for Edds' starting spot.

Parry said: "We can't take a chance on Gareth so he won't be available on Saturday. We've got to decide between Alan Mahon and Charlie Barnett as to who replaces him."

On-loan Manchester City defender Shaleum Logan is available again after completing a two-match ban.

He could replace on-loan Leicester youngster Luke O'Neill at right-back, although Parry said: "Luke has done very well and Shaleum has a very tough job getting back into the team."

Striker Bas Savage is still not ready to be considered for action as he recovers from a long-term injury.
