The 27-year-old, who joined the club last season from Leicester, will miss the rest of the season due to a knee injury.
He announced on Twitter: "Absolutely gutted that I'm gonna miss this season but I'm sure the boys will turn it around and get us up there".
The club's manager is also sad that De Laet will miss and hopes he'll return as soon as possible.
"He's had a really positive impact within the group as well and has shown some good performances. He's a really likeable player to have around and has a great work ethic".
