The on-loan Derby defender, who has stated that he will consider a move to Wednesday over anyone else should he be made available in January, missed the West Brom game with back problem.
Beevers meanwhile was excellent at the Hawthorns on Tuesday but his inexperience could be his downfall as it is expected that Johnson should return.
Laws said: "Michael has been magnificent for me and Mark Beevers came in and did tremendously well against West Brom. He's put a doubt in my mind and that's a real positive for Beevers. He's certainly going to be the future of this football club."
Meanwhile, Richard Wood's surgery to repair a dislocated shoulder went successfully and he is expected to return sometime after the new year.
In other news, Glenn Whelan has earned his first call up to the Republic of Ireland 'B' squad to face Scotland at Airdrie on Tuesday 20th November.
