The Daily Mail calls it a broken patella — ouch! — and Watford said Chalobah suffered the injury in training.

Chalobah, 22, has started all five Premier League matches for Watford this season, and has been one of the better performers in the Hornets’ surprising start.
He could be out until 2018, though Watford’s performance director Gavin Benjafield is hopeful that’s not the case, via The London Evening Standard:
“Whilst we can’t put an exact timeline on his recovery, we are expecting to see him re-integrating into the squad well before the New Year.”
Watford does have depth at center mid, with its corps including Etienne Capoue, Will Hughes, Tom Cleverley, Abdoulaye Doucoure, and Ben Watson. Still, it’s a tall order replacing Chalobah and we’ll get our first look when Watford hits the Hawthorns to face West Brom on Saturday.
