Seahawks' Miller suffers concussion

Seahawks tight end Zach Miller has sustained a concussion in Seattle's preseason opener against the Tennessee Titans after catching a 14-yard pass from Matt Flynn.

Miller was injured early in the second quarter on Saturday night after getting hit by Terrence Wheatley and Kamerion Wimbley. Miller was woozy on the field and walked off with a trainer at his side.

Seattle coach Pete Carroll said the team doesn't believe it is a severe concussion but they will be following all protocols with Miller, who is entering his second season in Seattle. Miller had two catches for 23 yards on Saturday.
