UCLA left tackle Conor McDermott is “very questionable” to play against Cal this Thursday after spraining his knee, head coach Jim Mora said Sunday.

Arguably the best player on the Bruins’ offensive line, the 6-foot-9 redshirt junior missed the second half of this past Thursday’s 56-35 loss at Stanford. He was able to walk unassisted, but with a limp, after the game and had an MRI the next day.

“He was actually walking without a limp (today),” Mora said. “He has a brace on. We’ll just have to see.”

If McDermott doesn’t play, redshirt freshman Kolton Miller will be in line to make his first career start.

UCLA lost two other starters at Stanford. Offensive guard Alex Redmond, who injured his hand, participated in Sunday’s practice. Outside linebacker Deon Hollins, who is recovering from a knee injury of his own, went into practice briefly before leaving for treatment. Backup running back Nate Starks, who sustained a head injury at Stanford on Thursday, was not present.

Linebacker Kenny Young showed up to practice in street clothes after returning to Louisiana for his grandmother’s funeral.

“We’re a little beat up right now, but we’ll get healthy-ed up by Thursday, hopefully,” Mora said. “Have as many guys back as we can. The guys that can’t play, they’ll support the guys that are in there playing for them.”
