Star Magpies midfielder Adam Treloar has suffered another setback in his recovery from an injured hamstring, according to SEN's Sam Edmund.

With the season currently suspended, Treloar has much time to recover, however, his latest soft tissue issue is not ideal with players desperate to maintain pre-season fitness.

Treloar last week received medical advice on his latest hamstring trouble, which comes after he strained his hamstring in the Marsh Cup game against Richmond on March 1.

Last week, Treloar is understood to have re-injured his hamstring training at home last week.

This tear is in the same area of hamstring that required surgery in 2018 and it caused Treloar to miss the Pies' Round 1 victory over the Western Bulldogs.

All players across the competition are on individual training programs, with most at reasonable intensity considering many were at peak fitness coming out of the pre-season.

Players have currently been told that training will resume on May 4, a date that hasn't changed considering that the AFL will reassess restarting the season on May 31.
