The duo, both aged 20, will be training at Franklin's Gardens from today. Visser, a wing, and Batty, a hooker, both have first team experience in the Guinness Premiership and European competition and both were part of the successful Falcons side that won the Middlesex Sevens.

Both Visser and Batty will be eligible for selection for this weekend’s National League One trip to the Cornish Pirates.
