Wasps' Director of Rugby Ian McGeechan said: "At scrum half, Eoin is in a good position to captain the side. He is on top of his game at the moment and knows the priorities required of the team on Sunday."
His side are currently tenth in the league, two places behind London Irish, who are captained by Reddan's fellow Irishman Bob Casey. Casey will be making his 100th Premiership start for London Irish on Sunday.
