YOUNGSTER Jake Argent faces a lengthy spell on the sidelines after he suffered a serious knee injury at Cambridge Utd last weekend.

The 18 year-old was set to try and break into the first team this season, but ligamant damage means that ambition is on hold.

The striker had only just entered the action as a subsitute for Jonathan Téhoué at the Abbey stadium last Saturday when he fell awkwardly following a challenge.
