NFL suspended Seahawks DE Bruce Irvin four games for violating the league's policy against performance-enhancing substances.
Irvin has no plans to appeal, admitting he took the substance without a medical exemption. He'll participate in training camp and preseason, then be barred from all Seahawks activities until Week 5. Irvin, the 15th overall pick in last year's draft, registered eight sacks and a forced fumble as a nickel-rushing rookie. Seattle is deep enough to withstand Irvin's loss after adding Cliff Avril and Michael Bennett to their pass-rushing corps.

Seahawks signed sixth-round RB/FB Spencer Ware to a four-year contract.
Ware is a north-south runner with some bulk and toughness, and he's expected to spend the majority of his time at fullback with the Seahawks. We wouldn't expect him to see many carries outside of a few short-yardage situations.

Coach Pete Carroll expressed some reservations regarding second-round RB Christine Michael's pass protection.
As we see so often, blocking can be a stumbling block for rookie backs trying to climb the depth chart. ESPN's Mike Sando expects Robert Turbin to stick as Marshawn Lynch's primary backup. "[Michael] has not done as much pass protection work as we'd like," Carroll said. "When we looked at Robert last year, we felt the same way, but Robert came on really strong as a pass-blocker, so we hope to do the same thing with Christine." Michael remains a strong Dynasty stash as a more talented natural runner than Turbin.
