Many players attend the combine but just don’t participate in drills — which teams dislike. The latest is California center Alex Mack.

Mack said he sprained his ankle on Monday, which will prevent him from participating in drills this week in Indianapolis.

“While preparing for the combine on Monday with my trainer, I suffered a sprained ankle,” Mack said. “The injury isn’t serious, but unfortunately, it is going to keep me from working out this week in Indianapolis. No one is more disappointed than me, as I have been working tirelessly to further prove myself as a first-round pick. However, I don’t want to perform at anything less than 100 percent.

“I will complete my interviews here and return to my training in anticipation of a great Pro Day in Berkeley on March 18.”
