Worcester have announced the signing of prop Paul Andrew from Championship club Cornish Pirates for next season.
The Warriors have also confirmed a new contract for hooker Ollie Hayes, who joined them from Bristol in 2011.
"Paul Andrew is a player we've been aware of for some time," said Worcester head coach Richard Hill.
"We keep a track on the best players in each position and have seen Paul's progress in the RFU Championship.
"He is similar to George Porter in that he has massive potential and will only get better. Paul is another excellent product of Cornish Pirates, where he has been well coached and developed, and his attitude is excellent.
"In the front row you have got to do your apprenticeship and next year is undoubtedly a big season for Ollie.
"We feel he can make the step up to play first team rugby in the Aviva Premiership and that's why we've re-signed him.
"Now is the time for him to make the step up. This is not a decision we have taken lightly, but Ollie really is the modern day hooker and we have put our faith in him."
