Howe admits Chris Wood could also be in the squad.
He said today: "Bruno [Guimaraes] has trained with us. I had a couple of difficult calls in the international break to say various things had happened to players so we were concerned for Bruno, but he's come back. The scan was good so he has trained and trained well. It has been slightly disruptive for him because these two week. He's in the squad."
For Wood, he said: "He came off with a rib problem. Another player we will make a late decision on."
On Alexander Isak, he continued: "He picked up an injury training with Sweden. The scan doesn't look too bad so we aren't overly concerned that it's a long injury but with any muscle injury. He is out running on grass and looking good,"
And for an update on Allan Saint-Maximin, Howe added: "He is doing well. He had a period away, he has come back and is very close but it is how we view things. I am being vague but I'm being vague because there are a lot of player situations that are slightly unclear and Allan is one of them.
