Glyn Hobbs is poised to join reigning Carlsberg South West Peninsula League champions Bodmin Town just two weeks after leaving Tavistock for Plymouth Parkway.
The highly rated striker could be facing his former team-mates from Langsford Park when second-placed Tavistock travel to Priory Park today in the Peninsula League's top game.
Tavistock, who relinquished top spot to Launceston in midweek, face their toughest task of the season against Bodmin.
Darren Gilbert's outfit are unbeaten in their four League games but the Lambs travel to Cornwall with confidence high after a run of six League victories that shot them up to the top of the table before Launceston's 2-1 victory at Bovey Tracey last Wednesday.
Tavistock will be missing suspended midfielder Ian Rooke but otherwise have a full squad available, with manager Ian Southcott aware of the task that faces his side.
"Bodmin were always going to be the yardstick for everyone in our league and, even though they have played three games fewer than us, it is very pleasing to have built up an eight-point cushion and to put them under some pressure so early in the season," he said.
If Hobbs does not sign for Bodmin, then he will be in the full-strength Parkway squad that travels to Launceston.
"We have to forget the national cup competitions now and concentrate on getting more league points," warned Parkway boss Wayne Hillson.
Falmouth Town will have to put Wednesday's 5-1 hiding at St Blazey behind them when they entertain Elburton Villa at Bickland Park.
Villa will be without suspended midfielder Sam Khakbazan but they have goalkeeper Simon May returning from a holiday and are hoping that strikers Levi Landricombe (knee) and Sam Stevens (hamstring) will pass fitness tests.
Liskeard Athletic have lost the services of Kevin Kendall after the midfielder suffered a bad knee injury, but the Blues have central defender Jordan Pearce free of suspension for their trip to Camelford.
St Austell will be looking to take their run of victories to three when they entertain a Witheridge side looking to bounce back from last weekend's home loss to Falmouth.
The remaining 18 Throgmorton Cup first-round ties are scheduled for today, with possible upsets at Speeds Meadow and Gala Parc.
Struggling Premier Division outfit Cullompton Rangers entertain Budleigh Salterton while Porthleven, under new manager Dennis Annear, play host to another lowly Premier side, Penzance.
