Portsmouth centre-back Matt Clarke has signed a new contract with the League One club until the summer of 2020.
The 21-year-old has made 101 appearances for Pompey since initially joining on loan from Ipswich in August 2015 before making a permanent switch.
“I’m really pleased to have signed a new deal,” Clarke said.
“I originally arrived with the sole mission of helping get Pompey out of League Two. We’ve done that now, but want to continue that progression.”
