TAYLOR Adams' 2019 injury issues have continued with the Collingwood star dealing with a lower leg ailment.

After making only a brief appearance at training at Olympic Park on Monday morning, the tough midfielder emerged during Wednesday's session with his left foot in a moon boot.

At times Adams joined his teammates on the field as they huddled together to be addressed by their coaches before he walked off, seemingly without discomfort, to take an elevated view of proceedings.

The extent of the 26-year-old's problem is unclear, although it seems unlikely to ground him for long given Magpies football boss Geoff Walsh told AFL.com.au the club wouldn't be providing updates on individuals unless they had suffered a serious injury.

Nonetheless, it continues a frustrating period for Adams, who this year was restricted to just 12 of Collingwood's 24 games after suffering three injury setbacks.

After finishing second in the 2018 Norm Smith Medal in the Magpies' narrow loss to West Coast, the hard-nosed onballer appeared set for a career-best season. However, a finger tendon problem in his left hand sidelined him for the opening two rounds before a lingering groin issue cost him a total of 10 games in two stints.

A member of the Pies' leadership group and a potential future captain, Adams rose to the occasion in the qualifying final against Geelong, collecting 26 possessions (16 contested), nine clearances and two first-half goals to help lead his team to victory, before the team suffered a shattering four-point loss to his old club Greater Western Sydney in their preliminary final.

A bull-at-a-gate player and trainer, Adams this season expressed his bitter disappointment at being forced to watch on from the sidelines.

"I'm a shocking rehabber. I just get frustrated and feel like I'm missing out on a lot. I love training. It is tough … Sometimes you just get unlucky," he told SEN.
