Cowley has brought in left-back Riccardo Calder and goalkeeper Ross
Etheridge on loan from Sky Bet Championship side Aston Villa and League One
outfit Doncaster Rovers respectively.
A former England under-17 international Calder is a product of Villa's
youth and academy system and although he still to make his first-team bow, has
gained valuable experience during loan spells with Dundee and Doncaster.
Keeper Etheridge (pictured), meanwhile, started out at Derby County and loans with
Ilkeston FC, Gresley Rovers, Leek Town, Crewe Alexandra and Stalybridge Celtic
followed before he signed for Accrington Stanley in the summer of 2015.
He joined Doncaster twelve months later and recently had a month with
National League North side Alfreton Town.
Both players have been given permission by their parent clubs to play for
City in the FA Cup and Buildbase FA Trophy and both will be at Sincil Bank for
the remainder of the season.
