New signing John Halls will go straight into the Brentford squad for tomorrow's trip to Chesterfield.

The former Stoke and Reading right-back signed for the Bees until the end of the season - but with a get-out clause that he can leave if a higher-division club comes in.

His arrival will give boss Andy Scott a chance to keep regular right-back Adam Newton on the right wing, where he played the second-half against Lincoln last week.

Winger Marvin Williams, who Newton pushed up from right-back to replace last week, is expected to miss the Saltergate trip.

Kevin O'Connor will also miss the game as he serves the last of his three-game suspension.
