OXNARD, Calif. -- The Dallas Cowboys, who hope to sign right guard Zack Martin to a long-term extension this summer, have agreed with their prospective right tackle, La'el Collins, on a two-year extension worth up to $17.4 million, sources told ESPN, confirming multiple reports.
Collins was set to be a restricted free agent after this season, but he is now signed through 2019. He is guaranteed $9.5 million at signing and will also receive a $4 million signing bonus, a source said.
Collins' base salary will increase each year, from $1 million in 2017 to $4.5 million in 2018 and $6.5 million in 2019. If he plays in 85 percent of snaps in 2017 and 2018, his 2019 base salary will jump to $8.5 million.
In 2015, Dallas signed Collins to a fully guaranteed contract worth roughly $1.6 million. He fell from being a projected first-round pick to an undrafted free agent after Baton Rouge, Louisiana, police questioned him about a shooting death.
"Definitely means a lot to me," Collins said. "Means a lot to my family, in so many ways for me and my family, man. I'm super excited and I'm just happy that I get to be with the Cowboys for the amount of time that I do and I look to really be here forever. So I'm going to continue to do what I got to do to make that happen."
Collins, who was set to make a $615,000 base salary this year, started 14 games at left guard in his first two seasons. With the retirement of Doug Free, the Cowboys moved Collins to right tackle in the offseason. He played left tackle his final two seasons at LSU.
On Sunday, executive vice president Stephen Jones said the Cowboys were optimistic they could reach a deal with Martin this summer. Martin has been named to the Pro Bowl in each of his first three seasons and was an All-Pro pick last year.
The Cowboys have All-Pro left tackle Tyron Smith under contract at $12.2 million per season and All-Pro center Travis Frederick signed to a deal worth $9.4 million per season. As one of the best guards in football, Martin is looking at a deal worth roughly $12 million per year as well.
