Port Adelaide forward Lindsay Thomas has been reported for bumping Geelong's Scott Selwood in the second quarter of their clash at the Adelaide Oval.

Thomas is likely to come under sanctioned by Match Review Officer Michael Christian, after running past the ball and electing to bump Selwood.

Selwood was initially rocked by the bump, before eventually walking off with the help of trainers.

Selwood was later spotted on the bench in a tracksuit top, signalling the end of his evening.
