Portsmouth boost ranks after sealing deal for promising keeper Duncan Turnbull

The giant American has agreed terms to the end of the season, with the Blues holding an option to extend that stay for another year.

Turnbull has impressed on trial and Kenny Jackett ran the rule over him in a 3-1 loss to the Royal Navy at HMS Temeraire on Tuesday afternoon.

And now the University of Notre Dame graduate will be tasked with intensifying goalkeeping competition, with Alex Bass and Craig MacGillivray the existing first-team options.
