London Irish have signed three players on short-term deals in preparation for the LV= Cup first round.
Ben Toolis, Ben Lonergan and Danny Kenny will all be involved in the squad against Newcastle on Sunday.
Australian-born lock Toolis is on a one-month loan from Edinburgh Rugby.
Flanker Kenny signs on trial after spells in his native Ireland with UCD, Leinster and Munster, while fellow back row forward Ben Lonergan joins on a two-week loan from Rosslyn Park.
"The LV= Cup presents us with an opportunity to mix the squad up," said London Irish director of rugby Brian Smith.
"We have players injured or missing through international duties in both the second row and back row. Ben Toolis will plug a gap in the second row and Danny and Ben will get their chance in the back row."
