Last month Morrison was granted leave by Simba SC management until the end of this season, travelling to Ghana to take care of his family problems.
Simba SC Chairman Murtaza Magungu said they had no information about the player submitting a request for a release letter, and they were surprised to see the information spreading so fast on social media.
Mangungu said Simba SC is aware that Morrison is still the team's legitimate player, it has not confirmed that it has parted ways with him.
"Morrison is still a Simba SC player, we are surprised to see reports of the footballer asking for a release letter, we gave him permission to go to his home for family problems," the official revealed.
The official pointed out: "The contract between Morrison and Simba SC has not expired, he continues to earn his dues as an employee of this club, we have never reported anywhere that we will not continue with him.''
''We have no information of him being in the process of signing for another club,'' the official maintained.
In another development, Namungo FC's assistant coach, Jamhuri Kihwelo has admitted that their chances of finishing in the top four of the 2021/22 NBC Premier League are fading after losing two games in a row on the outfit's home turf.
Namungo FC had on Monday lost 1-0 to Coastal Union in a league match held at Ilulu Stadium, Lindi, and before that the former went down 2-1 to Polisi Tanzania.
Kihwelo said his players lacked composure in the match against Coastal Union despite getting a lot of chances.
The tactician revealed the results were part of football, considering that no team is expected to win every match.
"Let's face it- it's football because sometimes we score three goals but sometimes we do not, there are times a club wins and there is the time it succumbs to a loss,'' the trainer pointed out.
"Our goal is to finish in either third or fourth spot in the league but with these results, I think now the chances are slim.''
Kihwelo pointed out: ''We will nevertheless keep on working hard in the remaining two matches and, in the end, we will know what position we are in."
Namungo FC has two remaining away matches against Mtibwa Sugar at Manungu Complex venue on June 26 and a clash against Mbeya City FC at Sokoine Stadium on June 29.
The Lindi outfit has collected 37 points to sit fifth, staying level with sixth-placed Coastal Union on points.
Azam FC occupies the fourth spot having collected 40 points, a place below third-placed Geita Gold FC boasting 42 points.
