Howler by athletics supremo about game making a comeback (6)
I believe the answer is:
coyote
'howler' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for coyote that I've seen before include "Wolf-like animal" , "North American wild dog" , "Wolf-like wild dog" , "US wild dog" , "North American prairie wolf" .)
