Wear, the team's third-leading scorer, has missed the last two games because of a sprained foot suffered last Saturday during practice. He went through UCLA's walk-through on Friday, and Howland said he would start against the Wildcats barring any setbacks.
"Travis is probable for giving it a go tomorrow," Howland said of his 6-foot-10 post player, who is averaging 11.6 points and shooting 51.5 percent from the field.
Muhammad, UCLA's leading scorer and second in the Pac-12 with 18.3 points per game, sprained his ankle in the first half Wednesday against Arizona State.
He played 18 minutes in the second half and all five minutes of the overtime period, but after scoring 15 points in the first half he had only six points on 2-of-5 shooting after halftime. Howland said the star freshman definitely would play Saturday.
"The sprain swelled up more than we anticipated," Howland said. "He was out there gingerly [in practice] but he will play."
UCLA (21-7, 11-4) plays Arizona (23-5, 11-5) in a pivotal game for both team's chances at winning the conference title. The 6 p.m. PT game at Pauley Pavilion will be televised by ESPN, and the "College GameDay" crew will be on hand.
