Isaiah Sykes had 21 points and 14 rebounds, and Keith Clanton added 18 points and 13 rebounds as Central Florida held on to beat Houston 74-63 Wednesday night.
The win extends the Knights (13-3, 3-0 Conference USA) winning streak to five games, a season-best.
The victory is also UCF's 15th straight at home, dating back to last season. They are 10-0 at UCF Arena this season.
The Cougars (9-7, 1-2) got 19 points form Alandise Harris and 12 from TaShawn Thomas, but lost their second straight game after having a season-best five-game win streak snapped last week at UTEP.
UCF coach Donnie Jones also served the final game of a three-game, school-imposed suspension Wednesday for his involvement in an NCAA investigation that revealed players and recruits received improper benefits.
