Play wearing medical dressing that's really strong tissue (8)
I believe the answer is:
ligament
'really strong tissue' is the definition.
'ligament' can be an answer for 'tissue' (ligament is a kind of tissue). I'm not certain of the 'really strong' bit.
'play wearing medical dressing' is the wordplay.
'play' becomes 'game'.
'wearing medical' becomes 'lint' (I can't explain this - if you can you should believe this answer much more).
'dressing' indicates putting letters inside (inserted letters are dressed or clad in others).
'game' placed into 'lint' is 'LIGAMENT'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for ligament that I've seen before include "Fibrous tissue joining bones or cartilage" , "What footballer may damage" , "Link between bones or cartilages" , "Band of tissue joining bones" , "Tough fibrous tissue in the body" .)
