Morkel was approved by the BBL Technical Committee to re-join the Heat squad after his spot was taken by a local replacement player while the fast bowler was completing his recovery from ankle surgery.
He has been training strongly over the past 10 days and will come into contention for the final squad of 13 tomorrow night.
With Mujeeb Ur Rahman departing for International duties, Morkel's inclusion is the only change to the Heat squad.

The Heat remain one of the competition’s most watched teams with three games this season being decided on the final ball.
Last Sunday’s thrilling encounter against the Sydney Sixers at Metricon Stadium was the second highest rating game for BBL|10 and the most watched match for the season in Queensland, with an average audience of 1.012 million viewers tuning into the game’s final overs.
The match also had a free to air reach of 2.33 million on Channel Seven, the highest for BBL|10.
The Heat have now played in the second and third highest rating games on Channel Seven for the season, plus BBL|10’s second and third highest rated Fox Cricket exclusive matches.
Brisbane will be on the road for the next week, with tomorrow's Renegades clash one of three Heat games which have been re-scheduled to new venues.
The other two games see the Heat travel to Adelaide next week to play the Strikers at home instead of at the MCG while the January 26 match against the Perth Scorchers set down for the SCG will be played at another venue to be decided.
