The pair will go straight in to the squad for tonight’s game against Cleethorpes Town, subject to FA approval.
Manager Spencer Fearn said: "Both Dan and Akeem are very exciting prospects and have played U23 and reserve team football. With Hugo out for the foreseeable future we needed to move fast and I know how highly rated Dan is at Hillsborough, so we are delighted he is with us.
“In terms of Akeem, due to our close links with Rotherham United we have been aware of his progress and he is a very good full back who will add further competition for places in our squad.
“Our thanks go to Steve Haslam at Sheffield Wednesday and Matt Hamshaw and Richard Hairyes at Rotherham United for making this happen.”
Meanwhile, club analyst Dale Whitfield will leave the club after tonight’s game to move to Japan to complete his PhD.
He will be replaced by Ben Nicholson, a UEFA A licence candidate, who works with Fearn in the Sheffield Wednesday Youth Development Phase at Hillsborough.
