Inverness Caley Thistle boss John Robertson has added two more players to his squad as he continues to build for the 2017/18 season.
Left-sided defender Riccardo Calder, 21, joins the Highland club from Aston Villa, having previously played on loan for Dundee, Doncaster Rovers and Lincoln City.
The other new boy is 20-year-old centre-half Matty Elsdon, who arrives at the Ladbrokes Championship side on loan from Middlesbrough.
