They may be confined to teams in trouble (7)

I believe the answer is:

inmates

I'm a little stuck... Click here to teach me more about this clue!

'they may be confined' is the definition.
The definition suggests an adverb but the answer is not.

'teams in trouble' is the wordplay.
'trouble' indicates anagramming the letters.
'teams'+'in'='teamsin'
'teamsin' with letters rearranged gives 'INMATES'.

'to' is the link.

Can you help me to learn more?

(Other definitions for inmates that I've seen before include "Prisoners" , "Inhabitants" , "Ties man (anag.)" .)

I've seen this clue in The Globe and Mail.
