Dolphins Edge Bradley Chubb will remain on the physically unable to perform list at the start of the regular season, HC Mike McDaniel announced Monday. That's not a surprise, as Chubb continues to work back from a late December ACL tear. But it confirms that he'll miss at least the first four regular-season games.

Per Jordan Schultz, the Miami Dolphins have signed DE Emmanuel Ogbah. The signing comes only a few days after DE Shaq Barrett abruptly retired. Ogbah had 24.5 sacks, 5 forced fumbles, and 1 INT in his previous four seasons with the Dolphins.

The Dolphins spent the 21st pick of the NFL Draft on Edge Chop Robinson. After a year at Maryland, Robinson closed out his college career with tow years at Penn State. He totaled 60 tackles, 11.5 sacks, and 20.0 tackles for loss across his three seasons. Robinson delivered a 97th-percentile speed score at 254 pounds at the Scouting Combine. We're a little concerned that Robinson won't claim high enough snap shares to produce consistent fantasy stats.
