The Seahawks added to their offensive line depth on Tuesday, activating rookie guard Phil Hayes from the physically unable to perform list. Rookie receiver Gary Jennings was waived to make room on the 53-man roster.

Haynes, a fourth-round pick out of Wake Forest, had sports hernia surgery in the offseason, causing him to open the year on PUP, but has been practicing the past three weeks. This week marked the deadline for the Seahawks to decide on activating Haynes and fellow rookie Demarcus Christmas, who remains on PUP as of Tuesday.

When the Seahawks picked Haynes on Day 2 of the 2019 draft, Seahawks coach Pete Carroll said, "Phil is a guy that we targeted early because of his makeup and his style of play. We're really excited about how our guards have been playing. You saw us go out and get Mike Iupati to go along with what D.J. (Fluker) has done. We thought early on that this is a guy that can fit in the mold of that. He's going to be 340 pounds. He's a really strong, really physical guy. He likes to finish blocks and knock guys down. He's got an attitude about him. He just looked like he would fit the bill to compete with those guys. We've been shifting gears here the last couple of years here and this is an indication of that. It was really a guy that we had sighted from early on and John figured out where he would go and we were able to nail it specifically because of his makeup that kind of matched up with the guys that we've had some success with and we're excited about it."

Jennings, also a fourth-round pick, had been inactive for every game this season, and with the addition of Josh Gordon late last week, the Seahawks had eight receivers on the roster prior to this move.

The Seahawks also made a change on the practice squad, bringing back defensive tackle Bryan Mone, an undrafted rookie out of Michigan who started the year on the 53-man roster, and releasing receiver Cody Thompson.
