Northampton Saints have signed Italy hooker Marco Manfredi for the rest of the season. The 28-year-old has moved to Franklin's Gardens from Treviso-based Benetton and will link up with compatriot Danilo Fischetti, who joined Saints in April. Manfredi will help fill the gap left by Curtis Langdon, who recently had an operation on his shoulder. Northampton director of rugby Phil Dowson said: "Given Curtis' injury and Robbie Smith is coming back from a long-term ACL injury, we needed another number in the hooker area. Northampton are away to Gloucester on Sunday, having drawn their first league game of the new season 33-33 against Exeter.
