Aaron Wilson at the National Football Post is reporting that the deal is for four years, and includes base salaries of $320K, $405K, $490K and $575K, with bonuses and escalators that can boost his pay as he works into the team's defensive line rotation.
Carrington, 23, was drafted No. 72 overall this past April to play defensive end in the team's new 3-4 defense. The 6'5", 284-pound project appeared in 44 games at Arkansas State, recording 146 tackles, 40 tackles for loss and 21.5 sacks in his illustrious career. That includes 33.5 tackles for loss and 19.5 sacks over his final two seasons, when he emerged as a starter.
The rookie will compete with Spencer Johnson for playing time behind projected starters Dwan Edwards and Marcus Stroud, and could see more playing time as the season progresses and he gets acclimated with the new techniques he'll be learning.
Buffalo has just two remaining unsigned rookies - running back C.J. Spiller (No. 9) and nose tackle Torell Troup (No. 41) - with ten days to go before training camp opens.
