Fourteen months after a blood clot threatened Jason Pinkston’s life and career, he’ll be back in the starting lineup.

Coach Rob Chudzinski said Pinkston will start at left guard Sunday when the Browns (4-9) face the Chicago Bears (7-6) in the final game this season at FirstEnergy Stadium. Pinkston will fill in for John Greco, who was ruled out with a sprained medial collateral ligament he suffered this past weekend in a 27-26 loss to the New England Patriots.

“It’s been so long,” Pinkston said Friday. “Especially anything you love, [if] you get a chance of losing it, it’s emotional when you get back.”

Pinkston will start for the first time since Oct. 14, 2012, when he left a game against the Cincinnati Bengals because he felt ill. He then missed the final 10 games last season after a blood clot was discovered in his lung, and he sat out most of this season after suffering a high-ankle sprain Aug. 15 in an exhibition game.

On Sunday, Pinkston appeared in his first game this season. He rotated at right guard with starter Shawn Lauvao and later replaced Greco after he left in the second quarter.

“It’s been a long road, a tough road for him going back to the embolism and then getting back to the point during training camp where he was feeling better,” Chudzinski said. “You could see him getting back to normal, and then he has the high-ankle sprain. So we got him back, and he’s been through a lot. I’ve really been impressed with his attitude, how he’s worked [in] the weight room, all the extra things, the rehab, he was in there non-stop, and in the game [Sunday], you could see he was excited about playing again. So I feel good for him. He did a good job last week, and he’s had a good week of practice.”

Pinkston conceded he’s still trying to knock some rust off.

“I thought I did pretty good in the pass game,” he said. “In the run game, I really didn’t help myself too much or the team. That’s just from being out and not really doing it as much. I’ve been working on it this week, so it should be better.”
