Steelers coach Mike Tomlin at Notre Dame pro day, Tuitt in boot, Nix weighs in at 331 pounds

Steelers coach Mike Tomlin continues to rack up the frequent flier miles, this time, hitting up South Bend, Ind., to watch Notre Dame's pro day.

The two names that will come up first are those of nose tackle Louis Nix and defensive end Stephon Tuitt.

Stephon Tuitt is here and has a walking boot on. Underwent a procedure to correct the stress fracture in his left foot last week.

Blue and Gold Illustrated reporter Andrew Owens also tweeted Tuitt is in a walking boot after having surgery on his left foot last week.

Obviously, any speed drills for Tuitt would produce unreliable times. The interviews, though, will be big.

Tuitt's stock has cooled a bit over the draft prep period, some in part due to his injury.

Nix had something of the same issue, and without workouts to help boost his somewhat underwhelming 2013 film, he'll need to show his worth during his last workout before the draft.

Nix reportedly weighed in at 331 pounds, as well.
