A six-pack of Dolphins notes on a Tuesday:
u25aa The Dolphins, searching for defensive help, are signing veteran linebacker Martrell Spaight, according to a source, and also are planning to add a defensive end in the wake of injuries to William Hayes and Andre Branch.
Spaight, selected in the fifth round of the 2015 draft by Washington, played three seasons for the Redskins but was released Sept. 1.
He had 75 tackles in 15 games last seasons, including six starts. An outside linebacker at Arkansas, he switched to inside linebacker with Washington.
Spaight, 6-0 and 243 pounds, has no career sacks and one career interception, in 2016 against then-Green Bay quarterback Brett Hundley.
