INJURY-PRONE Collingwood midfielder Daniel Wells is relatively confident his troublesome calves will not cause him more major problems, declaring them "the least of my worries".

Wells played just 10 games in his first season since crossing over from North Melbourne.

The 32-year-old twice had stints out of the senior side with injuries to both calves, while a thigh injury prematurely ended his year. 

Wells told collingwoodfc.com.au he hadn't had recent concerns but acknowledged it was tough to predict when he would be struck down. 

"The times it (calves) went, I felt great and you're sort of a bit scared when you come back into training and then play games. You're just not quite sure," Wells said. 

"This year, it's been pretty steady. There's still the unknown. You can put in as much work as possible but sometimes you can get caught at a wrong angle and it can go. 

"But, I haven't felt it at all. I've felt pretty strong and it's the least of my worries at the moment."

Collingwood coach Nathan Buckley said last February Wells' three-year, $1.8 million deal would be a "massive success" if the silky onballer lined up in 15-16 games per season. 

The former Roo has played 253 career games since he was drafted with the second overall selection in 2002. 

Wells has managed fewer than 20 matches in eight of his 15 seasons.
