Boothroyd told the club's official website: "He has been brought to my attention and I like what I've seen of him in training.
"He can play in both full back positions and is a player who I believe we can mould into another really good player for the club. Morten is a really good prospect, who I hope can break into the team during the rest of this season."
On young defender Bender, Boothroyd added: "One of the things a club like ours has to rely on is its youth policy.
"Tom is yet another player to come off our production line. We were keen to tie him up, because he's a player who has already been training regularly with the first team and is a really bright prospect."
