Team appears one by one (6)

I believe the answer is:

eleven

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

'team' is the definition.
(I know that eleven is a type of team)

I cannot understand how the rest of the clue works.

(Other definitions for eleven that I've seen before include "XI as Roman numeral" , "Bingo's "legs"?" , "Cardinal" , "Number, on a team maybe" , "Time for morning coffee" .)

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