Jack Viney shines but Jack Watts leaves Melbourne training session early

JACK Viney made an instant impression at training today but Jack Watts left the track early with a groin complaint.

MELBOURNE'S father-son gem Jack Viney has wasted little time making a big impression on his new teammates.

The hard-nut midfielder was a standout with his ferocious attack on the ball at training today.

The man who looms as a bargain No.26 pick for the club is headed for a likely Round 1 debut for the Dees.

Viney, and another new recruit, David Rodan, from Port Adelaide, were the two who impressed most in the session which focused on the Dees' stoppage work.

But there was some concern for former No.1 draft pick Jack Watts, who walked off the track late in the session with a groin concern.

Watts appeared to be in some discomfort as he ended his session feeling the right side of his groin.

Watts sought the immediate attention of the club’s doctor and physio.

Veteran Aaron Davey also appeared to struggle with his fitness as he continues to recover from a left knee problem.

The Demons midfielder had his knee taped and limped at times during the two-hour work-out at Gosch’s Paddock.

The 158-gamer played eight games last season and has a battle on his hands working his way back into the Demons’ best 22.
