Adelaide defender Andy Otten and midfielder Cam Ellis-Yolmen have both signed one-years deals that will see them stay at West Lakes in 2019.

Ellis-Yolmen will remain on the club's rookie list, while Otten will enter his 12th season in the AFL.

“Both Andy and Cam are valuable contributors on and off the field and over the years have overcome adversity with injury, which is a testament to their character and resilience,” Adelaide's General Manager List Management and Strategy Justin Reid told afc.com.au.

“We see them both playing a meaningful role going forward.”
