The striker, who has six goals to his name this season, had already been assured of his place before his impressive appearance off the bench against Manchester United on Tuesday night, an appearance which included a fine 25-yard strike just after the hour mark.
“Scoring a goal like that will have him in confident mood and scoring a goal like that at Old Trafford is something he won’t forget,” said Bruce.
“Matty was excellent when he came on. I told him after the semi-final that he would be playing (in the final) so I’m not going to break my word on that.
“He will play as long as he is fit. He did enough in the semi-final to warrant his place.”
Two other players hoping to be in with a shout of selection for the biggest game in the Tigers’ history are continuing to make good progress.
Paul McShane gained further game time as he played an hour in a behind-closed-doors game on Tuesday while goalkeeper Allan McGregor is pushing for a return from broken ribs and a damaged kidney.
“Paul came through another hour of football and we’ll take a look at him to see if he’s available for the weekend (against Everton),” added Bruce.
“Allan is on course and he trained on Tuesday. We’ll see how he is over the next couple of days and he’s got a chance.
“But I’m not really a gambler. To play football at this level you have to be 100 per cent. They’ll all want to play, but I have to make the right decisions. It would be foolish of me to risk three or four, but we’ll see.”
James Chester is another who will hope to be available following scan results on the hamstring injury sustained against Aston Villa last weekend.
“The scan has confirmed that James has a tear in the hamstring, although it’s not as bad as the last two times,” revealed Bruce.
“He’s got ten days and we’ll give him every chance.”
