"His availability will be in question for this week, so I would say he's doubtful (for the game Saturday at Indiana)," Brooks said.
The coach also noted that freshman cornerback David Jones likely will miss a few days of practice with a hip flexor, the same injury that kept freshman offensive lineman Sefo Blaylock from playing Saturday.
"McClinton was running toward the ball. A guy was blocking him high and he puts his hands on him and the other guy's knee hit his knee and his went out," Brooks said. "Cook's knee just buckled as he was starting to make a cut. It buckled before he was hit high. It's freakish how it happened."
McClinton is out for the season, Cook for at least four to five weeks.
Receiver Keenan Burton broke a bone in his foot and will need surgery this week. He's also going to be out for a month or more.
If that's not enough, Brooks today listed receiver Glenn Holt as doubtful to questionable for the game at Indiana because of his ankle sprain and said defensive end B. Jay Parsons is doubtful because of the same injury.
If that's not enough, UK already had lost defensive tackle Lamar Mills (knee) for the year with an injury suffered in the first game and defensive tackle Ricky Abren, who may play at Indiana, has been out both games with a broken wrist. Another defensive tackle, Jason Leger, missed the Louisville game and played only briefly against Idaho State.
"It's amazing how freakish some of the injuries have been this year," Brooks said.
How amazing? Well, remember that the Cats are also without three other players — linebacker John Sumrall, linebacker Dennis Johnson and special teams specialist Andrew Hopewell — because of injuries that ended their careers in the spring.
And don't forget running back Tony Dixon, who broke his ankle last month.
That's six players already out for the season and two more — Cook and Burton — who will likely miss half the season or more. For a team short on numbers, that's near impossible to overcome because all eight players would have been playing.
Brooks says the playing surface at UK is not to blame for the injuries as some have speculated.
"No. It is freak deals. Two kneecaps. That's just very, very strange. Natural grass is supposed to be the safest thing. We have just hit an unusual stretch of bad luck, I guess. I don't know. It's a shame. Guys were playing hard and doing really good things."
Now other "guys" have to do a lot more for Kentucky to salvage its season.
"We just have to have guys step up and fill in for the guys that are injured," Brooks said.
He'll give running back Draak Davis a look at receiver this week with Cook, Burton and Holt injured. True freshman DeMoreo Ford also will become a key player. But the player Brooks says the Cats need to elevate his play now is sophomore speedster John Logan.
He got in for one play Saturday and couldn't hold on to a catch on a play where Idaho State was called for pass interference.
"John Logan has worlds of potential but has yet to achieve that and play to his ability or speed," Brooks said. "John needs to step up and it would be nice if he did because he has speed. He's just been inconsistent in practice."
Brooks says Logan has had trouble running the right routes. "He just has to do things the right way and he doesn't always do that," Brooks said.
Sophomore Dicky Lyons is not possible help, either. Brooks said his pulled left hamstring is still so bad that he could not played now if he wanted. He's still scheduled to be redshirted.
