Cowboys left tackle Tyron Smith signed an eight-year contract extension that will keep him in Dallas through 2023.

The total value of the deal is worth $109 million with $40 million guaranteed and a $10 million signing bonus, sources said Wednesday. Smith will make $32 million in the first three years of the new contract.

The ninth-overall pick of the 2011 draft, Smith made the Pro Bowl last season. In May, the Cowboys picked up the fifth-year option on his rookie contract. Before Tuesday’s news dropped, Smith’s 2015 salary was to be fully guaranteed for $10.039 million, which is equal to the 2014 transition tag for offensive linemen. Smith was set to make a base salary of $2.079 million in 2014.

After he was drafted three years ago, he signed a four-year, $12.5 million contract that was fully guaranteed and included a $7.6 million signing bonus.

Smith, 23, is the foundation of the Cowboys’ rebuilt offensive line. He has started all 47 games in which he has played and has conceded only 14 sacks in his career, according to STATS LLC.

“I haven’t gone team by team and evaluated everybody, but we think he is an outstanding player,” head coach Jason Garrett said last December.

“He’s done a really good job for us. He’s a heck of a run blocker. He’s a heck of a pass protector, and he plays a really important position. We are really fortunate to have him.”

The Cowboys made it known they were to complete a contract extension with Smith in 2014. Now they will turn their attention to lengthening receiver Dez Bryant’s deal. He is scheduled to become a free agent in 2015.

Because of his youth, solid work ethic and consistency protecting Tony Romo’s blindside, Smith became a valuable piece that Cowboys management felt could be an asset to the team for more than a decade. On Wednesday, Dallas committed to a future with Smith as its left tackle.

And amazingly enough, he will only be 33 if he remains with the team through the end of the deal he signed Wednesday.

8 years?

Dayum. That nigga good tho.

Most people in the NFL normally never live out a contract THAT long. Either they retire, get cut cause of cap reasons or get traded.

For a franchise QB, I can see making that kind of a long-term investment. But for an O-Linesman? No way. lol

Well keep in mind he's a Left Tackle. Which are usually considered a key part of the team.

you guys are being dumb

8 years with only 40 million guaranteed is a steal for a top left tackle they said, "it's one of Jerry's best moves ever"

I think it's a great move. tbh.
