Richmond forward Ben Lennon will have surgery this week on the AC joint in his right shoulder.

Lennon suffered the injury at training last week and will undergo minor clean-up surgery.

Richmond’s General Manager of Football, Dan Richardson, said the 20-year-old would be sidelined for 4-6 weeks.

“Ben is a talented young player who we rate very highly, and unfortunately hasn’t been able to get a lot of continuity in his football this season,” Richardson said.

“The Club will continue to support him with his rehab, he’ll overcome this setback and return to be an important player for us in the back end of the season.”
