DEFENDER Seb Tape is being monitored by the club’s medical staff after going down mid-way through the second quarter against Port Adelaide at AAMI Stadium.

The South Australian required stitches to his head following a head high hit by Power midfielder Hamish Hartlett.

The collision forces the GC SUNS to activate substitute Jackson Allen into the contest. 

Tape has been in superb form in recent weeks after returning from a long-term ACL injury.
