Tierney ruled out of Hatters visit

Tierney was sent off for collecting two yellow cards - the second for kicking the ball away - in Saturday's 2-2 draw at Oldham and serves a one-match ban. John White switched flanks to fill in at left-back after the red card and is set to deputise again with Phil Ifil returning on the right. The U's will also be without young winger Medy Elito, who serves the second game of a three-match ban, while on-loan midfielder Josh Payne has gone back to West Ham. Kem Izzet will push for a start in midfield having come on as a substitute at Boundary Park following illness.
