I believe the answer is:

removal

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

'eviction' is the definition.
(thesaurus)

'sleep at sporting venue' is the wordplay.
'sleep' becomes 'rem' (abbreviation for Rapid Eye Movement).
'at' means one lot of letters go next to another.
'sporting venue' becomes 'oval' (I can't explain this - if you can you should give a lot more credence to this answer).
'rem'+'oval'='REMOVAL'

'after' is the link.

Can you help me to learn more?

(Other definitions for removal that I've seen before include "Expulsion" , "Extraction" , "Taking (of thing) away" , "Ejection" , "Change of location" .)

I've seen this clue in The Daily Express.
