He's out of practice (5)
I believe the answer is:
rusty
I believe this clue is a double definition.
'he's' is the first definition.
'out of practice' is the second definition.

(Other definitions for rusty that I've seen before include "(Of iron) corroded" , "Behind the times" , "Reddish," , "Antiquated" , "affected by inactivity" .)
