Coventry City have signed Southampton defender Jordan Turnbull on a three-year deal for an undisclosed fee.

Former England Under-20 centre-half Turnbull failed to make a senior appearance for Southampton.

The 21-year-old spent the last two seasons on loan at Swindon, playing in a total of 86 League One games.

"Jordan played twice against us last season and impressed me both times with his accomplished performances," said manager Tony Mowbray.
