Pompey have completed the signing of Stephen Henderson.
The former Bristol City goalkeeper has put pen to paper after passing a medical.
The Irishmanwas at Wellington Sports Ground today training with his new team-mates.
The Robins were keen to keep the highly-regarded 23-year-old and had offered him a new two-year deal.
They will now be entitled to compensation as Henderson, who was a free agent, is under the age of 24.
