If you had Danny Shelton in Patriots-turned-Lions bingo, you win.

The Detroit Lions agreed to terms with another ex-Patriot on Wednesday, reaching a deal with the defensive tackle on a two-year contract worth $8 million, his agent, Drew Rosenhaus, said.

Shelton, the 12th overall pick by the Cleveland Browns in 2015, spent the past two years in New England and is coming off the best season of his career, with 61 tackles and three sacks in 14 starts.

Shelton, 26, is the second defensive tackle and second ex-Patriot the Lions have added this week as part of their offseason defensive overhaul.

On Monday, the Lions landed ex-Patriots linebacker Jamie Collins and former Chicago Bears defensive tackle Nicholas Williams on multiyear deals.

Collins, who, unlike Shelton, played for Lions coach Matt Patricia in New England, is expected to replace Devon Kennard at one starting outside linebacker spot, while Williams should play at least a rotational role on the defensive line.

The Lions entered free agency wanting to sign at least two interior defensive linemen. Last month, they cut Damon Harrison, another Rosenhaus client, and are not expected to re-sign pending free agents Mike Daniels and A'Shawn Robinson.

The 345-pound Shelton should replace Harrison as the primary nose tackle. He has just 4.5 career sacks but is considered one of the NFL's better interior run defenders.

Even with Shelton and Williams in the fold, the Lions have room to add one more defensive lineman through free agency or the draft. They own the No. 3 pick in the first round, and No. 35 early in Round 2, which could be a sweet spot for a defensive lineman.

At No. 3, the Lions will consider Auburn defensive tackle Derrick Brown, who has drawn comparisons to Ndamukong Suh for his disruptive skill as an interior pass rusher.

Along with Shelton, Collins and Williams, the Lions have agreed to contracts with free agents Chase Daniel and Halapoulivaati Vaitai. Daniel is expected to back up quarterback Matthew Stafford, and Vaitai projects as the Lions' new starting right tackle.

Players could sign deals with new teams beginning at 4 p.m. Wednesday.
