The Dallas Cowboys signed right tackle La’el Collins to a two-year contract extension, the team announced Tuesday.

The deal is worth $15.4 million, a source told NFL Network’s Mike Garafolo.

Collins was entering the final year of his rookie deal and would have been a restricted free agent after this season.

The lineman’s contract has been a complicated matter since he entered the NFL. Once considered a possible first-round pick, Collins became involved in a murder investigation prior to the 2015 draft (for which he was ultimately fully exonerated) and wasn’t selected. He was signed by the Cowboys to a three-year, $1.6-million deal, which is better than most undrafted free-agent contacts, but certainly undervalued him.

Collins started three games at guard for the Cowboys last season and is expected to start at right tackle in 2017. With an average annual value of $7.7 million per season, he’s the second highest-paid right tackle in the NFL.
