LT Jonas Jennings was named one of the team captains in a vote among his teammates a couple weeks ago. But it’s obvious that 49ers coach Mike Nolan is getting frustrated that Jennings has spent so much of his time with the team on the sideline.

Jennings missed 13 games last season with a torn labrum in his shoulder. He has missed all or parts of four games this season. The latest injury that kept him out of the lineup was a wrist sprain. When Nolan was asked last week if it’s a severe wrist sprain, he answered, “No.” He also had surgery early last week to repair a ligament in his pinkie finger.

I am certainly not questioning the severity of Jennings’ injuries. Heck, I sit behind a computer all day, so the only physical risk I face is a case of hemorrhoids.

I don’t know if Nolan would like to see Jennings play through these injuries or if he’s trying to light a fire under him. But Nolan has voluntarily brought Jennings’ name into the conversation whenever he has been asked whether Adam Snyder will replace RT Kwame Harris.

“Right now, he’s going to work at both tackles,” Nolan said of Snyder. “He’s going to compete for the tackle position on both sides. Today, he was at left, because Jonas still isn’t practicing yet. But, he’s going to compete for both tackles.”

Remember, the 49ers made a huge commitment to Jennings prior to last season, signing him to a seven-year, $36 million contract. The 49ers awarded him a $12 million signing bonus – the most the organization has ever spent to attract a free agent from another team.

Now he is competing for his job.

“I’ve got to get the best guys on the field,” Nolan said. “I think competition makes you better.”

Snyder was considered the favorite to win the job at RT when training camp began, but he was sidelined with a strained bicep and missed a good portion of camp. Now, Jennings is the one who has been unable to “compete.”

“He can’t compete while he’s on the sideline watching,” Nolan said. “That’s kind of how Snyder was taken out of the mix on the right side. He wasn’t competing, because he was injured in training camp.”
