CHICAGO -- The Chicago Bulls say first-round draft pick Lauri Markkanen is day-to-day because of back spasms.

He left practice Friday.

The No. 7 overall pick, Markkanen was acquired along with Zach LaVine and Kris Dunn from Minnesota for Jimmy Butler in a draft-night trade.

The 7-foot Finn averaged 15.6 points and shot over 42 percent on 3-pointers in his lone season at Arizona.
