The Hornets beat Forest 3-1 at the City Ground to keep their promotion hopes very much alive - Slavisa Jokanovic's men are just a goal behind Norwich City in the Championship, level on points with the Canaries.
Nottingham Forest, however, suffered another far-from-satisfactory result, with Wilson leaving the field of play after tangling with Odion Ighalo as early as the first half.
Freedman, though, wants '100 per cent commitment' from his players and insists that's exactly what his defender was offering him against Watford.
And he also revealed why Wilson's season isn't really over - albeit not from a playing point of view (his suspension sees him banned from Forest's remaining games).
The Forest boss told reporters after the Watford loss: “I tell the players to live on the line. I want 100% commitment. Sometimes you’re going to go over the line and he’s done that tonight.
“He’s been fantastic for us and shown he’s willing to put the effort in day in, day out.
“His season’s over from a playing point of view but his support is still needed in the dressing room and on the training ground.”
The loss leaves Nottingham Forest winless in five consecutive league games now, a run that would be disturbing boss Freedman and the club's fans considerably more at any other time of the season.
At the moment, though, the focus for Forest is firmly on next term, with there being no chance of reaching the play-offs in their remaining three games.
