Dave Lyons has signed a short-term deal with London Irish.
The former Worcester and London Scottish lock will bolster the Exiles’ options in the second row, a position where the club has been hit with injuries.
Director of Rugby Brian Smith said: “Dave is a physical, ball carrying second rower who has amassed plenty of experience from his time playing for Clubs in both the Premiership and Championship.
“There is plenty of rugby to play in the next couple of months so Dave will get an opportunity and I’m sure he’ll do well.”
