While they await word from Ray Allen and Shawn Marion, the Cavaliers added some insurance in the middle Monday.
The Cavs signed 7-foot, 245-pound center Alex Kirk, likely for the league minimum of $500,000.
Cleveland’s roster now stands at 17, pending the Kevin Love trade, but general manager David Griffin may not be done yet.
There were reports over the weekend that the 39-year-old Allen is considering playing another season, and the Cavs are considered the favorite to land the shooting guard for the veteran minimum of approximately $1.4 million. The Los Angeles Clippers could also make a run, as they are led by Doc Rivers, who coached Allen in Boston.
Marion, a 36-year-old who can play both forward spots, is also considering signing with the Cavs for the veteran minimum. Cleveland is viewed as the favorite, but Indiana can offer more money.
Kirk, a University of New Mexico product who went undrafted in 2014, will battle veteran Brendan Haywood for minutes behind expected starting center Anderson Varejao.
Kirk played for the Cavs in the Las Vegas Summer League, averaging 5.2 points on .524 shooting and 3.4 rebounds in 15.4 minutes.
The 22-year-old averaged 10.0 points, 6.8 rebounds and 1.7 blocks in 101 games for New Mexico, where he was a two-time Mountain West Conference All-Defensive selection.
Kirk is extremely long — he has a wingspan of 7-3½ and a standing reach of 9-1½ — but also considered slow-footed.
Kirk, who red-shirted his first season at New Mexico while recovering from back surgery, is also considered a decent mid-range shooter.
Haywood, 34, was acquired in a draft night trade with Charlotte. The 34-year-old missed all of last season due to a stress fracture in his foot.
