Former North Melbourne star Nick Dal Santo says Collingwood knew they were taking a massive punt on Daniel Wells when they brought him to the club.

The 33-year old injured his foot during his side's Queen's Birthday win over Melbourne, and is set to miss the rest of the season after requiring surgery.

And Dal Santo, a former teammate of Wells at North, thinks the Pies' heavy investment in the injury prone veteran has not yet paid off.

“They (Collingwood) knew what they were purchasing when they got ‘Wellsy’ from the Kangaroos,” he told SEN Afternoons.

“If they were prepared to pay him that money off the history he had with injuries while at the Kangaroos, then you have got to take the good with the bad.

"That’s an investment, and if it pays off it's great, at this stage it probably hasn’t.

“Well done to ‘Wellsy’ for trying to come back on, because that probably hasn’t been one of the ways he has gone about his football in the last three to four years while he has been severely injured.

“He’s a man who knows his body, and unfortunately he knows it because he has been through so many injuries.”

Wells has only played 14 of a possible 44 games for the Pies since crossing over from the Kangaroos at the end of the 2016 season, being hampered with injuries.

He has one more year to run on a three-year $1.8 million dollar contract he signed with Collingwood as a free agent.
