He was admitted on Friday after suffering back pain and breathing problems, which was later diagnosed as Viral Meningitis.
But after a visit from a consultant tonight, Macca was told that he could go home to recover.
The Town stopper is now hoping to recover in time to play some part in the Mariners' pre-season campaign, targeting a return in the home friendly game against Peterborough United on Tuesday week.
Meanwhile, the Mariners have arranged a friendly fixture at Brigg Town on Wednesday night (7.30pm). Paul Hurst has promised that some of his first team will be involved against the Zebras.
Admission will be £5 Adults and £3 Concessions.
