Hall suffered a hamstring injury that kept him out for weeks. He made his return from injury, starting the whole game, in a 2–2 draw against Blackpool on 24 November 2012. Following this, Hall started in the next six matches for the club until he suffered a hamstring injury and was substituted in the 42nd minute, during a 3–1 win against Brighton & Hove Albion on 29 December 2012. After being sidelined for weeks, Hall made his return from injury against Nottingham Forest on 26 January 2013, coming on as a 70th-minute substitute, in a 1–0 win. He then started in the next three matches for Watford until suffering another hamstring injury that kept him out for a month.
