The Dallas Mavericks will be without Maxi Kleber for the foreseeable future after the German forward tore his right hamstring in practice on Tuesday.
The Mavericks released a statement on Thursday saying treatment options are being considered and there is no timetable for Kleber's return.
Kleber has appeared in 22 of Dallas' 28 contests this season and is averaging 6.2 points and 3.5 rebounds in 25.6 minutes per game off the bench.
He had been playing well since missing four games last month due to a lower back contusion sustained on a hard fall against the Los Angeles Clippers on November 15.
In nine games since returning, Kleber was averaging 8.8 points, 3.4 rebounds and 1.4 blocked shots while shooting 59.6 per cent from the field and 46.9 per cent (15 of 32) from three-point range.
Kleber appeared in all 18 playoff contests for the Mavericks last season during their run to the Western Conference finals, averaging 8.7 points and 4.6 rebounds in 25.4 minutes per game during that stretch.
Dallas (14-14) currently sit in third place in the Southwest Division and ninth in the West.
