Newcastle Falcons have signed flanker Todd Clever following his departure from Japanese side NTT Shining Arcs earlier this year.
The USA international, and former national team captain, played Super 14s in South Africa with the Lions and at North Harbour in New Zealand.
"He is a physical defender and a powerful attacker," director of rugby Dean Richards said.
Despite featuring in three World Cups, Clever was omitted from the 2015 squad.
He said: "The club is expecting big things in the next few years and I'm looking forward to it.
"It's good to be in the situation as a new player coming in where people expect big things."
