Leicester-born Cockerill-Mollett is a product of the club's Academy having made his way through the ranks to sign professional terms in August 2016, before going on to make his first-team debut during a 5–2 EFL Trophy victory over Grimsby Town later that month.
The 21-year-old former Republic of Ireland youth international made fifteen first-team appearances during an injury hit 2019/20 and will no doubt be keen to add to that number during the upcoming campaign.
Following the decision to award Callum with a new deal, manager Darrell Clarke has now challenged the youngster to go on and establish himself as a first team regular this season.
Speaking via the club's official website, Clarke said; "Callum has all the attributes to be a top defender. This is the season he really needs to establish himself as a first team regular with that undoubted ability he has.
"He was a little unfortunate last season when playing very well to pick up the injury when he did and I know he is raring to kick on again in the new campaign."
