The Patriots and tackle LaAdrian Waddle have agreed to a two-year deal, per Mike Reiss of ESPN.com (on Twitter). The deal, which quietly took place on Tuesday, includes a $250K bonus and gives the lineman $2.425MM before incentives, Tom Pelissero of USA Today tweets. 
Waddle, a former undrafted free agent, was cut by the Lions in December after playing two-plus seasons with the team. Soon after, he was picked up by the Patriots. The 24-year-old (25 in July) has battled injuries in recent years, including a torn ACL in 2014. Last year, Pro Football Focus (subscription required) rated Waddle as the worst qualified offensive tackle in the NFL with an overall grade of 23.5.
Specific terms of the deal are not yet known, but I would expect that a large portion of Waddle’s contract will be non-guaranteed. Waddle will likely compete for a reserve tackle role in camp this summer.
