Watford will play Coventry City in a pre-season friendly but it will take place at Boreham Wood's Meadow Park rather than Vicarage Road.
Beppe Sannino's Golden Boys will take on Steven Pressley's Sky Blues on Wednesday, July 30 with kick-off at 7.30pm.
Tickets for the match will be £16 for a seat, £12 for an adult standing and £8 concession/under-16/OAP standing. They can be bought from Boreham Wood's box office website now and Watford's ticket website towards the end of June.
Watford traditionally only play one game at Vicarage Road during pre-season, usually their final first team match, due to regeneration work on the pitch and they face Udinese at the stadium on Saturday, August 2.
The Hornets development team's game with Boreham Wood has been brought forward a day to Monday, July 28.
