Joins the team? (5)
I believe the answer is:
yokes
'joins the team?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for yokes that I've seen before include "Oppresses" , "couples" , "Harnesses (oxen)" , "Crosspieces fastened over the necks of a pair of draft animals" , "Harnesses together" .)
