The Seahawks placed McIntosh (ACL) on the active/PUP list Monday, John Boyle of the team's official site reports.
McIntosh is continuing to recover from a left ACL tear suffered last July, and it appears the issue will cause him to miss at least the early portion of training camp. Once he's healthy enough to practice, though, McIntosh will be eligible to come off the PUP list at any point during camp. If he were to need more time to recover late when rosters are reduced to 53 players in late August, though, McIntosh would have to miss at least four regular-season games on the reserve/PUP list.
