The Seahawks are bringing back linebacker Mike Morgan, according to his reps at Reign Sports (on Twitter). It is expected that Morgan will join Seattle for practice on Monday. 
Morgan, 29, was technically the Seahawks’ starting strongside linebacker in 2016, but he didn’t see a ton of snaps since the team spent lots time in the nickel formation. He was also held back by injury, spending eight weeks on injured reserve with a sports hernia. All in all, Morgan played only 138 defensive snaps and posted just ten tackles.
The Seahawks project to start Cassius Marsh and K.J. Wright at the outside linebacker spots. Seattle also added a pair of free agent OLBs in David Bass and Terence Garvin. Morgan will compete for one of those backup spots, potentially unseating one of the two spring additions.
The Jaguars and Saints were the only teams known to have worked out Morgan this offseason.
