The midfielder played from the start for the 3-1 triumph.
Dyche said: “I'm really pleased for Jimmy," added the manager. “He works ever so hard. We ask a lot of him.
“When I left him out [in recent weeks] I'm told him he's one of our future players like Patto [Nathan Patterson] but they have to go in and out of the team as part of their learning. He's got a lovely honesty about him, he's a very good player, and he's very adaptable as we've seen.
“There were a lot of good performances. I thought Doucs was excellent. He set the scene very early on with his pressing and work ethic for the team.
“The delivery was very good, as they were generally today from set pieces. That's a key factor, to put it in the right areas with quality because we know we've got people who can go into the box with that belief of scoring. I'm pleased we did that today."
