The promising onballer played a key role in Hepburn's 2019 grand final charge and was a mainstay for the Greater Western Victoria Rebels in the NAB-League.

Redan president Gary Goyne said he would add depth to the Lions as a goalkicking midfielder.

"He's the right age profile for us," he said.

"He's got pace and strength over the ball, he has a good pedigree, and we hope we can make him a better footballer and person at the end of the day."

Grant will join fellow St Pat's students Cooper Craig-Peters and Cooper Atchison at Redan, where he is expected to slot into the midfield along side stalwarts Lachie George and Liam Hoy.

Goyne said the 18-year-old had fielded offers from other clubs, but was keen to play with his mates.

"It's worked out well for both us and him," Goyne said.

"He's excited to be playing with his mates and ready prove a few people wrong who may have overlooked him.

"Hopefully he can perform for us and go forward in the future."

Grant is one of three Redan players taking part in pre-season training with North Melbourne's VFL squad.

Goyne said any high-level exposure the players could bring back to the club would only benefit it on the field.

"We are excited that these boys are getting an opportunity to show their worth at that level," he said.

The signing is the latest in a series of moves from the club to help bolster its potency in attack.

Last month the club signed CHFL tall-forward Harry McKimmie, who was the leading goalkicker for Dunnstown three years in a row.

Redan coach Jarrett Giampaolo said McKimmie's inclusion would mean a more dynamic forward line, especially with the experience he would add alongside their young forwards.
