By the close of business on Thursday, Tasracing was none the wiser about the fate of the meeting postponed from Mowbray on Wednesday night or the meeting scheduled for Elwick on Sunday.

It all hinges on a coronavirus test from Victorian jockey Mark Zahra who travelled on the same commercial flight as an infected person on March 12.

Tasmanian jockeys Anthony Darmanin and Craig Newitt have since ridden in races in Victoria where Zahra was also involved.

Although they are not believed to have had any direct contact, it's enough to have dragged Tasmania into a wait-and-see situation.

Zahra's test result was expected to be known by midday Thursday but this was later changed to "late Thursday night."

Tasracing said it would make a further announcement on the two thoroughbred meetings as soon as that result was known.

It added that: "The Launceston meeting remains suspended with the intention to reschedule as appropriate."

Rising star Cool Water Paddy faces his toughest test to date in the $12,000 Launceston Mile at Mowbray on Sunday night.

His task has been made a little easier by the absence of Ryley Major, but he still faces a quality, albeit small, field.

Trained by Juanita McKenzie at Magra, Cool Water Paddy has won his past eight starts but is stepping up to open company for the first time.

Connections were believed to be considering sending him to Melbourne for a race at Melton last week but aborted the plan due to the coronavirus restrictions.

He has drawn the pole in the Launceston Mile where his six rivals include his new stablemate Shelby Bromac.

The Victorian six-year-old , previously trained by David Aiken, is a class act when right and last month finished second in the Echuca and Albury Cups.

He scored his biggest win in Hobart 12 months ago when he beat War Dan and Star Chamber in the $75,000 Tasmania Cup.

The two highest-rated runners in Sunday night's field are Devonport Cup winner Illegal Immigrant and Call Me Hector.

Longford trainer John Blacker will continue his association with apprentice Ianish Luximon in the two main races at Elwick on Sunday.

Blacker will utilise Luximon's 4kg claim on Blaze Forth who has 63kg in the Open Handicap and Zatacla who has 62kg in the Benchmark 84.

Luximon rode his second career winner on the Blacker-trained Silver Road at Elwick on March 4 and followed up with a win on stablemate Silzoar at Mowbray three days later.

He has six rides at Elwick including four for Blacker.

The 22-year-old from Mauritius is now with Adam Trinder at Spreyton.

Brandon Louis, who is also from Mauritius, has been booked for eight rides at the meeting.

Louis was due to make his Tasmanian debut at the Mowbray meeting on Wednesday night.

After an extended stint in Western Australia, he has had his indentures transferred to Cressy trainer Cameron Thompson for the next two years.

Thompson expects Louis to make his mark in Tasmania.

"He's a great young man and a hard worker," the trainer said.

The Hobart harness meeting on Friday night has been promoted to Sky 1 to replace Geelong harness which was cancelled due to a coronavirus issue.

Main race on the program is the $8100 Cascade Draught 3YO which opens proceedings at 6.40 pm and will see the fourth Tasmanian appearance of the Kate Hargreaves-trained Dyslexic.

So far the Victorian has managed three seconds including a narrow loss to Micton Mouse in the $30,000 Tasmanian Derby and a second to Kadar at Mowbray last Sunday night.

He had to race outside the winner all the way last week and, although he had every chance, Kadar did get home in 57.3 seconds so there was some merit in Dyslexic's effort to go down by only 2.5m.

However it's doubtful that punters will be keen to take $1.30 again this week.
