Irving injured his shoulder against the Milwaukee Bucks, came back the next game and then re injured himself upon his return. While Scott claimed he would be cautious with Irving before bringing him back the first time I'll assume he means it this time.
The Cavaliers are about to embark on a very busy part of their schedule so while it appears that Lester Hudson can do a job for the team it will be nice to get Irving some more minutes when he returns probably around the weekend.
Varejao has been out long-term but has participated in some practices lately. Scott told the Plain Dealer this about Varejao's progress:
"Just because he's anxious doesn't mean he's ready. He told me a couple of weeks ago he was bored and wanted to get out on the court. We're not going to rush him. If he said that thing is a little sore, then we'll wait and continue to do what we've been doing as far as his rehabilitation goes."
I'd imagine Varejao will just get a few games in the last 7-10 days of the regular season at most. The Cavaliers have not played any true centers lately and have started Tristan Thompson at center for the last stretch of games.
