CLEVELAND, Ohio -- Cleveland Cavaliers head coach Larry Drew said Tuesday night he “wouldn’t completely rule out” the possibility of backup point guard Matthew Dellavedova missing the remainder of the 2018-19 season because of a concussion.

“I think there’s a chance,” Drew said prior to Tuesday’s matchup against the Boston Celtics. “I wouldn’t completely rule it out. There hasn’t been any discussion about it, but I believe there’s always a chance.”

Dellavedova will miss his 10th straight game Tuesday night because of the tough blow he took against the Miami Heat on March 8. Considering all the factors involved -- the tricky nature of concussions, the league’s strict protocol, Dellavedova’s concussion history and the Cavs having just two weeks remaining -- Drew said the team will be cautious when it comes to bringing Dellavedova back.

“You just never know as far as a recovery time," Drew said. "It is protocol and we will allow him to take as long as he needs until he is ready to even just come out on the court and go through shooting with us. He hasn’t even been able to do that yet. There’s really no timetable and no real rush right now. We’ll see how he is as each day goes by and we will just allow him to take as long as he needs to get right. This is not the first time it’s happened to him so you have to use extra precaution in bringing the player back that has had that injury before.”

Shortly after the injury occurred, Dellavedova felt woozy. Earlier this month, he was so sick he returned home from the team’s three-game road trip against Philadelphia, Orlando and Dallas.

On Tuesday, Dellavedova was able to go to the practice facility, but he hasn’t been able to take the court for non-contact shooting sessions.

Dellavedova arrived from Milwaukee in a trade almost midway through the season. In 36 games with the Cavs, Dellavedova is averaging 7.3 points and 4.2 assists.
