Tua Tagovailoa's knee issue hasn't caused him to miss any reps during practice this week.

While Alabama's sophomore QB is dealing with a sprained knee, Crimson Tide coach Nick Saban said Wednesday night that Tagovailoa has taken every rep in practice this week.

"He's been able to do all the work in practice, so that's not an issue," Saban said.

In addition, Saban gave an update on left guard Lester Cotton.

The senior sustained a mild ankle sprain during Alabama's practice on Tuesday and didn't practice Wednesday.

"Hopefully he'll be able to get back to practice tomorrow and we'll be fine," Saban said.
