"We were high on Robby when he was being drafted, I know that from talking to our scouts back then," Detroit coach Jeff Blashill told the Red Wings website. "I know we've been high on him at different times, listening to our pro scouts over the years in our pro meetings. We're hoping we can get Robby back up to the speed he was when he first came into the League and he had lots of success.
"… We need more scoring, he can potentially provide that, so I look forward to watching him play."
Fabbri had an NHL career-high 37 points (18 goals, 19 assists) in 72 games as a rookie in 2015-16.
"He's a great kid and a hard-working guy," St. Louis coach Craig Berube said. "He fell on some injuries around here, and we wish him all the best."
De la Rose, who did not play in the Red Wings' 5-1 loss to the New York Rangers, has four points (one goal, three assists) in 16 games this season. The 24-year-old forward had nine points (three goals, six assists) in an NHL career-high 60 games with the Red Wings last season after he was claimed off waivers from the Montreal Canadiens.
Selected by the Canadiens in the second round (No. 34) in the 2013 NHL Draft, de la Rose has 32 points (12 goals, 20 assists) in 195 regular-season games and no points in 12 playoff games.
"He's a big center/winger ... Smart hockey player, good skater," Berube said of de la Rose (6-foot-3, 215 pounds). "We'll see when he gets here, and we'll take a look at him and see where he fits in."
