Andre Gray and Craig Cathcart are doubts for Watford’s clash with Cardiff.

Striker Gray limped off after just 31 minutes of the Hornets’ 4-1 win over Preston last Saturday with a hamstring issue and missed the goalless draw at Nottingham Forest on Wednesday night.

Defender Cathcart suffered a similar problem to Gray’s one minute from time at the City Ground.

Defender Adam Masina plus midfielders Will Hughes and Tom Cleverly have all returned to training and could play a part on Saturday.

Cardiff manager Neil Harris could have Greg Cunningham back.

The defender has not played since October 18 due to a hamstring injury, but has been in recovery and could feature in Harris’ matchday squad.

Defender Jordi Osei-Tutu is unlikely to return before Christmas because of a hamstring issue.

Forward Lee Tomlin is also set to remain sidelined with a groin problem.
