With a huge sigh of relief, Baylor remains undefeated.

Late in regulation, Perry Jones III was lying on the ground in pain, grabbing his knee after colliding with a BYU player. He needed assistance to get off the court.

But moments later, he checked back into the game and tipped in a shot, which helped the sixth-ranked Bears secure an 86-83 victory over the Cougars and remain undefeated.

Jones scored a career-high 28 points, including six during a comeback Baylor (9-0) had to put together after falling behind at halftime.

Brady Heslip added 18 points on 6-of-10 shooting from three-point range, and Pierre Jackson scored 13 for the Bears. Both made a number of crucial shots down the stretch.

Matt Carlino and Brandon Davies both had 18 points to lead the Cougars (8-3), who had won their last four.
