The Los Angeles Rams have agreed upon a four-year, $42 million contract extension with Alec Ogletree.

The deal contains $33 million over the first three years and he becomes the NFL's second-highest paid inside linebacker behind Luke Kuechly.

Ogletree, currently playing on the fifth and final year of his rookie contract, was originally drafted 30th overall by the Rams in 2013 and has totaled 443 tackles in 57 career games. 

While the Rams paid Ogletree a significant salary, the franchise must also sign Aaron Donald to what could be the NFL's richest contract for a defensive player.
