Melbourne coach Dean Bailey was asked on Tuesday if Watts was a chance to play his first game for the Demons on June 8, the club's annual Queen's Birthday clash against Collingwood at the MCG.
But Bailey said form and timing would dictate when Watts plays.
"Jack's game on the weekend was okay [for Casey Scorpions]. He'll get another game this weekend at VFL level and if he plays well, then we'll consider him," Bailey said at the Junction Oval.
"He's a very busy man, Jack, he's got a lot of things going on in his life, let me tell you.
"The challenge for Jack is just to get some consistency and to manage his time, which he's doing really well and hopefully he'll play well in the VFL this weekend.
"That'll put some pressure on us, not just for the following week, but for the weeks after that … when he's ready, we'll pick him and when that time comes, we'll let you know."
Casey Scorpions coach Peter German told melbournefc.com.au that Watts, who had 22 disposals and took seven marks against North Ballarat, was encouraging last weekend.
"Although his preparation has been a little bit behind the rest of the group, he was very good," German said.
"We pushed him up into the midfield and he showed poise, steadiness and composure in tight situations.
"He's still developing and the next phase for him is to take marks and kick some goals up forward. Other than that, he's coming along very well."
