Exeter City have signed former Scotland midfielder Kevin McDonald and Championship striker James Scott from Hull City for an undisclosed fee.
He spent eight months out following a kidney transplant in April 2021.
The midfielder, who won five caps for Scotland previously played for Burnley, Sheffield United, Wolves and Fulham in the Championship and Premier League.
"He'd been in at other clubs but felt the fit at Exeter was right for him," said manager Gary Caldwell.
"He has real character and the knowledge and expertise he can pass on to the other midfield players will be invaluable for us.
