Depending on variety of factors including how he trains, the Magpies could decide to hold him back an extra week meaning he would not play until April 20 when the Collingwood VFL team plays the Northern Blues at Victoria Park.
In the final year of his three-year contract Wells could still pose a significant threat to the opposition with the new 6-6-6 rules expected to suit his capacity to explode from the centre square.
The dual best and fairest winner in 243 games with North Melbourne has played in just three losses in his 14 games at the Magpies.
Collingwood’s strong midfield was well beaten in round three against West Coast with Magpies coach Nathan Buckley saying they lost key contests.
Speedster Travis Varcoe, who was carryover emergency last week, and Callum Brown – who played in round one – are expected to vie for selection this week however Brayden Sier, who played in last year’s grand final, missed the VFL last week with a minor rib injury which restricted his breathing.
Meanwhile Chris Mayne, who arrived at the Magpies via free agency at the same time as Wells, plays his 200th game on Friday night against the Bulldogs.
After battling for a spot in his first season, Mayne was a revelation last year, playing 21 games including a strong grand final. He was also very good against Richmond in round two.
The Western Bulldogs plan to play premiership ruckman Tom Boyd in the VFL against Collingwood on Friday as he returns from a back injury that kept him sidelined from the first three rounds.
