The ATLANTA HAWKS welcome back the Boston Celtics to the Highlight Factory. The pressing question is whether Kevin Garnett will grace the court or if the Celtics will face the Hawks without him. The first couple of meetings between the Hawks and Celts this month ended in two victories for Atlanta, both at home and away. Will Atlanta end January 3-0 against Boston? Green fans are optimistic that the Celts will pull this one out. $10-$200. 7:30 p.m. Philips Arena, 1 Philips Drive. 866-715-1500. www.hawks.com.
