Pompey have completed the signing of midfielder Michael Doyle.
The 33-year-old has penned a one-year deal at Fratton Park after leaving Sheffield United at the end of last season.
Doyle – who has one Republic of Ireland cap – came through the ranks at Celtic, but moved south of the border to join Coventry in 2003.
He made almost 300 appearances for the Sky Blues and had a spell on loan at Leeds before signing for Sheffield United in January 2011.
Doyle netted 10 goals in 231 games for the Blades and was part of the side that reached the League One play-offs and Capital One Cup semi-finals last term.
