NASHVILLE, Tenn. (AP) — Seattle coach Mike Macdonald said Sunday night that rookie linebacker Bud Clark will miss months with a broken right ankle, while offensive lineman Mason Richman suffered his own “long-term injury” in the Seahawks’ preseason loss to Tennessee.

“Two guys that we love, that play our style of ball, that are our type of guys,” Macdonald said of Richman and Clark. “Teammates love ’em, great teammates, great guys, great football players. They have great futures. It’s a heartbreaker, honestly. We’ve had three heartbreakers this week, which is tough.”

Seahawks wide receiver Jake Bobo was carted off the field Friday from Seattle’s joint practice with the Titans and was placed on injured reserve Saturday.

Richman went down on the opening drive and was helped to the sideline after getting his right leg checked while laying down on the field. Macdonald said they have to figure out what the specific issue is, but he called it a “major injury, a long-term injury.”

On Seattle’s first defensive play, Clark broke his right ankle and Macdonald said he’ll miss months. Trainers put his leg in an air cast, and players from both teams came up to the rookie before he was carted off the field. Clark was Seattle’s second-round pick and 64th overall out of Texas Christian.

Linebacker Connor O’Toole said Clark’s injury is the type that almost takes the life out of a game.

“Just to know what he’s going to go through and the pain that he’s in, it’s just bigger than football at that point I feel like,” O’Toole said. “And your heart breaks for your brother, so it takes a minute to regroup as a team. We just lift him up and he’ll be in our prayers.”
