Seattle Seahawks free safety Earl Thomas just took a huge step in his recovery process.

Literally.

Thomas ran for the first time since fracturing his leg Week 13 in the Seahawks victory over the Carolina Panthers.

Via Instagram, Thomas posted a video of himself on the treadmill, “first day back running.”

Thomas had considered retirement after the injury, but recently told ESPN’s Ed Werder that he would return for the season.

“I’m coming back to prove I’m the best,” Thomas said. “I’m coming back to help my team win a championship.”

Coach Pete Carroll is hopeful that Thomas will be healthy to start the year.

“All indications are that he will make it back,” Carroll said at the combine. “He’s doing very well.”

Thomas had missed the first game of his NFL career the week before the fracture with a hamstring injury, snapping his streak of 106 consecutive regular season games played.
